delivered the opinion of the Court.
I FACTS
Greenbelt Homes, Inc. (GHI), the appellant and cross-appellee, is a cooperative housing development of some 1600 units located in Greenbelt, Maryland. All but a few of the houses were built by the federal government during the 1930’s and 1940’s; GHI, which is a non-profit, non-stock Maryland Corporation, acquired the property and began operating-in 1952. GHI retains legal title to the land and buildings, pays the taxes and insurance, and supplies maintenance and various other services. Funds for these services are obtained through monthly operating payments made by each member-owner. Through a mutual ownership contract, which is similar to a proprietary lease,
see, Green v. Greenbelt Homes,
Nyman Realty, Inc. (Nyman), one of the appellees and cross-appellants, is a real estate agency located in Greenbelt and the successor in interest to Greenbelt Realty Company. Although Nyman bought Greenbelt Realty on January 1, 1977, it continued to operate the business under the name "Greenbelt Realty” until January 1, 1978, when the name was changed to "Nyman.” Nyman has six offices in addition' to the one located in Greenbelt and is a member of both a national and a county listing organization. It deals in a variety of types of properties, including houses located in the GHI cooperative. At trial, the evidence showed that, at least since the early 1970’s, Nyman and its predecessor have each year listed and sold more GHI houses than any other single agency.
Eric Wade Barber and Marshal A. Gielen, two of the appellees and cross-appellants, are real estate agents employed by Nyman and member-owners of GHI. Both .earn substantial portions of their income from commissions on the sale of GHI houses. At the time of trial, Barber had contracted to sell his co-op house but had not yet settled; Gielen had listed her house for sale but had not yet obtained a buyer.
A GHI member-owner who wishes to sell his interest in his house can do so in one of three ways: (1) he can act as his own agent; (2) he can list with any licensed real estate agency; or (3) he can list with the sales office operated by GHI. Prior to June 1, 1978, upon completion of a sale, the selling member *45 paid GHI an administrative fee of $150 and an inspection fee of $65. These fees were intended to cover GHI’s costs in screening the proposed buyer, educating the buyer concerning his rights and obligations as a GHI member, completing the paperwork required to transfer the interest, and conducting a physical inspection of the house. If the selling member listed and sold his house through the GHL sales office, GHI charged a 5-V2% commission, approximately $1100 on the average house, but waived the administrative fee.
On June 1,1978, a reorganization of the GHI sales service, which had been approved by the GHI Board of Directors on January 12, 1978, became effective. This reorganization, which involved expansion of the sales staff, resulted in a significant change in the fees charged members who sold their co-op houses. The $65 inspection fee, previously charged on all sales, was abolished. The 5-V2% commission, previously charged those members who sold through the GHI sales office, was also abolished. The $150 administrative fee, previously charged on all sales but waived where GHI was paid a commission, was increased to $550 and charged to all sellers, regardless of whether or not they used the GHI sales service. The services of the sales staff were made available to all sellers without a separate charge. Testimony at trial indicated that the increased administrative fee was intended to cover the costs of all of the services for which the charges had previously been separate, i.e., screening, educating, completing paperwork, inspecting, and maintaining the sales office. GHI arrived at the figure of $550 by adding the costs of providing the services previously covered by the old administrative and inspection fees to the costs of operating the expanded sales office, a total of approximately $110,000 annually, and dividing that total by the number of houses transferred in an average year, approximately 200. Thus, GHI took two separate operations which, prior to the reorganization, were separately funded; merged them; and began levying a single charge which covered the costs of both operations. The principal economic effect of the reorganization was to compel all sellers to pay *46 to support the sales office, whereas previously only those sellers who utilized its services had had to pay for its support. This created, and was obviously intended to create, an economic incentive for all selling members to list their houses with the GHI sales office.
II PLEADINGS
On May 24, 1978, one week prior to the effective date of the GHI reorganization, Nyman filed a bill of complaint in the Circuit Court for Prince George’s County. The bill of complaint was subsequently amended and Barber and Gielen joined in the action as plaintiffs. As amended, the bill alleged that the combination by GHI of its administrative, inspection, and sales services in a single operation and the levying of a single mandatory charge covering the costs of the combined services violated the Maryland Antitrust Act (the Act), Md. Com. Law Code Ann. §§ 11-201 et seq., and was also ultra vires. Nyman, Barber and Gielen claimed that they had lost listings, sales, and commissions as the result of GHI’s combination, because selling members, who were compelled to pay for the GHI sales service whether they used it or not, were choosing to list their co-op houses with GHI, rather than with brokers such as Nyman. Pursuant to §§ 11-209 (b) (2) and 11-209 (b) (4) of the Act, the amended bill sought an injunction, treble damages, costs, and attorney’s fees.
Ill PROCEEDINGS
At trial, the chancellor found that GHI, by its combination of services and fees, had created a tie-in which was unreasonable per se and thus a violation of § 11-204 (a) (1) of the Act. 1 He also found that the imposition of the $550 administrative fee was ultra vires, although he held that the old administrative and inspection fees totaling $215, which *47 were charged prior to the reorganization, were not. Evidence presented at trial showed that, beginning at least five months prior to the effective date of the GHI reorganization, the number of GHI members listing their co-op houses for sale with Nyman had declined, with a corresponding decline in commissions earned by Nyman and its agents; the chancellor found that this decline had been caused by the loss of goodwill which accompanied Nyman’s name change on January 1,1978 and by a lack of available finance money. The chancellor therefore held that Nyman, Barber, and Gielen had failed to prove that they had lost commissions as a result of the tie-in. Barber, who had contracted to sell his co-op house and who had paid GHI the administrative fee of $550, was found to have suffered damages in the amount of $335, that figure representing the difference between the $550 fee charged and the "justified charges” of $215.
On the basis of these findings, the chancellor issued an order, dated January 4,1980, in which he enjoined GHI from charging its members an administrative fee which combined the costs of its sales service with its administration and inspection costs, from offering its sales service to its member-owners on other than an optional basis, and from subsidizing its real estate sales service with funds derived from any mandatory fees charged member-owners. In his order, the chancellor also awarded Barber damages of $1,005, i.e., three times his actual damages of $335, and ordered GHI to segregate the bookkeeping for its sales service from that of its other operations.
Both sides have appealed the chancellor’s order. GHI contends that the chancellor’s findings that the imposition of the combined fee was a restraint of trade in violation of § 11-204 (a) (1) and also ultra vires are not supported by the evidence. Nyman, Barber, and Gielen assert that the chancellor committed error in refusing to award damages for lost commissions; they argue in addition that the chancellor erred in finding that only a portion of the administrative fee was ultra vires; and he erred in denying attorney’s fees.
*48 IV THE LAW
In interpreting the Maryland Antitrust Act, we are to be guided, but not bound, by the construction given the analogous federal statutes by the federal courts. Md. Com. Law Code Ann. § 11-202 (a) (2);
Quality Discount Tires v. Firestone Tire,
It has been held that a tie-in, defined as "an agreement by a party to sell one product but only on the condition that the buyer also purchases a different (or tied) product, or at least agrees that he will not purchase that product from any other supplier,”
Northern Pacific Railway Co. v. United States,
V APPLICATION OF THE LAW
Turning to the facts of the case at bar, we agree with the chancellor’s finding that the combination by GHI of its administrative and sales services under the mandatory administrative fee was a tie-in which was unreasonable
per se
and an unreasonable restraint of trade under § 11-204 (a) (l).

It is clear that GHI linked two normally separate items in such a manner that the tying service, i.e., the administrative and inspection services, could not be purchased from GHI without also buying the tied service, i.e., the real estate sales service. The tied service is not one which is merely incidental or ancillary to the tying service, as is, for example, "free” delivery service provided by a department store for merchandise.
See, Fortner Enterprises v. United States Steel Corp.,
VI CONTENTIONS
(a) GHI argues at some length that the instant case is "substantially identical” to that of
Foster v. Maryland State Savings and Loan Association, supra,
where a savings and loan association required mortgage borrowers to pay, as a cost of obtaining the loán, an attorney’s fee to cover the cost of having the association’s counsel prepare the mortgage and examine title. Borrowers were free to employ counsel of their own choosing to perform these same functions on their behalf; but, the lender waived payment of the fee if the borrower chose to use the law firm selected by the lender and paid the firm for its services directly. It was alleged that this practice was an illegal tie-in of legal services to the sale of credit and an unreasonable restraint of trade. The D.C. Circuit held that the practice was legal. Finding that the legal services purchased were being provided to the lender, the Court held that, although charged separately, the services were an "incidental and inseparable part” of the purchase of the loan and not a tied product or service. As an essential element of a tie-in is the existence of two separate products or services,
see, Fortner Enterprises, Inc.
v.
United States Steel Corp.,
"GHI argues that its tie-in is based on legitimate business justifications. It contends that it wants to handle the sales itself to avoid misrepresentations and misconceptions regarding the nature of the real property interests being purchased and the nature and policies of the cooperative.
"This Court finds no legitimate business justification for the tie-in. In its screening and educating processes GHI can, and apparently does, apprise the prospective purchaser of the rights and obligations between member-owners and the cooperative. GHI can quite properly assess its selling member-owners to support screening and educating new members. The sales contracts are contingent on GHI’s approval. GHI can protect itself, its goodwill and its member-owners without the tie-in. GHI failed to prove that its real estate sales office was necessary or even helpful in the screening and educating processes. (Selling and screening could conflict rather than complement each other.)
"Additionally, GHI did not make itself the exclusive agent for the sale of the member-owner’s interest. Its intention was not to control outside agents but rather to establish a beachhead for itself in the real estate sales service market.”
Foster v. Maryland State Savings & Loan Association is thus distinguishable from the case at bar.
(b) GHI also contends that, in order to set forth a cause of action under the Act, there must be a showing that the alleged violation has caused some injury to the general public. Under its theory, where the only specific injury proved
*54
is economic injury suffered by the plaintiffs as individuals, no cause of action will lie. Again, we do not agree. The Act provides: "A person whose business or property has been injured or threatened with injury by a violation of § 11-204 may maintain an action for damages or for an injunction or both against any person who has committed the violation.” Md. Com. Law Code Ann. § 11-209 (b) (2). Absent from this section is any suggestion that injury to the general public is an element of a cause of action under the Act.
See,
Reynolds and Wright,
A Practitioner’s Guide To The Maryland Antitrust Act,
36 Md. L. Rev. 323, 347 (1976). In
Quality Discount Tires v. Firestone Tire, supra,
the Court of Appeals discussed at considerable length the elements which a plaintiff in a private antitrust action must allege and prove to recover under § 11-204 (a) (1) of the Act. Absent from the elements listed was any requirement of public injury.
Id.,
(c) The chancellor refused to award the cross-appellants damages for lost commissions, stating:
"This court finds that the plaintiffs failed to demonstrate that their losses in real estate sales commissions resulted from GHI’s tie-in. The loss of goodwill subsequent to the plaintiffs name change to 'Nyman Realty,’ coupled with the relative inaccessibility of financing due to tightening of the money market were largely responsible for the drop in commissions. Loss of listings cannot be measured in damages since, although it was asserted that listings were valuable, no specific value was testified to or demonstrated. It has not been proved with reasonable certainty that the tie-in resulted in a loss of sales commissions.”
In their cross-appeal, Nyman, Barber, and Gielen contend that the chancellor’s finding was contrary to the evidence. Although the Court of Appeals, in
Quality Discount Tires v. Firestone Tire, supra,
referred to the relaxed standards of proof employed in antitrust actions with regard to causation and the amount of damages,
(d) As we noted above, the chancellor held that the imposition by GHI of the $550 administrative fee was ultra vires, but that GHI could legally charge the selling members for the cost of performing those functions which had been covered under the old administrative and inspection fees. In his opinion, the chancellor based his holding that the combined fee was ultra vires upon Art. VIII, § 2 of the corporate by-laws, which provides that GHI "shall not have the authority to assess its members . . .”; the opinion does not explain why the chancellor concluded that GHI was not also barred under this section from assessing its members an inspection fee and an administrative fee which did not include the cost of the sales office. On this appeal, both sides argue that the chancellor’s holding is logically inconsistent. GHI contends that, if the by-laws do not bar it from assessing its selling members administrative and inspection fees, the by-laws do not bar it from assessing the members an administrative- fee which includes the cost of the sales service. Nyman, Barber, and Gielen contend that, if the assessment of the $550 fee is prohibited, the assessment of a lesser fee must also be prohibited. Both sides would have this Court interpret the language of the corporate by-laws and determine whether the imposition of either the old or the new fee is permissible. We do not reach the question.
In
Poole v. Miller,
"We have seen above that custom may have the force of a by-law; and a necessary corollary of that proposition is that a similar custom may also repeal a by-law. Consequently, long-continued disregard of the provisions of a by-law may be equivalent to an express repeal. Even a by-law which has been formally adopted may lapse or be repealed by desuetude.”211 Md. at 456 .
See also, W. Fletcher, Cyclopedia of the Law of Private Corporations, §§ 4183, 4200 (rev. perm. ed. 1966). In the case at bar, GHI has charged selling members an administrative fee since 1967. If the levying of this charge is prohibited by a provision contained in the by-laws, that long-ignored provision, like that in Poole, has "been waived or repealed by acquiescence.” Thus, we need not consider whether Art. VIII, § 2 of GHI’s by-laws, which the chancellor held barred the imposition of the $550 fee, bars the imposition of an administrative fee of a lesser amount, as Nyman, Barber, and Gielen contend. Similarly, as we have upheld the injunction issued and the award of damages to Barber based on the violation of the Antitrust Act, a reversal of the finding of ultra vires 4 would have no effect on the order issued and we need not address GHI’s contention either.
(e) The cross-appellants contend that the chancellor erred in failing to award reasonable attorney’s fees. Section 11-209
*58
(b) (3) of the Act provides: "If an injunction is issued, the complainant shall be awarded costs and reasonable attorney’s fees.” Section 11-209 (b) (4) provides: "In an action for damages, if an injury due to a violation of § 11-204 is found, the person injured shall be awarded... costs and reasonable attorney’s fees.” The statutory language is mandatory.

Case remanded for determination of attorney’s fees and costs and entry of appropriate decree.

Notes
. Section 11-204 (a) (1) provides: "A person may not: By contract, combination, or conspiracy with one or more other persons, unreasonably restrain trade or commerce.”
. 15 U.S.C. § 1 provides: “Every contract, combination ..., or conspiracy, in restraint of trade or commerce ... is declared to be illegal ....” Although the section does not expressly state that it bars only those practices which “unreasonably” restrain trade, the federal courts have so construed it. Quality Discount Tires v. Firestone Tire,
. Tie-ins may also be prohibited under § 11-204 (a) (6) of the Act. The chancellor held that, under the circumstances presented here, this section was inapplicable. The validity of that decision is not an issue in this appeal.
. We note the apparent misapplication here of the term ultra vires. An ultra vires act "is one not within the express or implied powers of the corporation as fixed by its charter, the statutes, or the common law.” Fletcher § 3399 (rev. perm. ed. 1978). As by-laws "are essentially separate and distinct from, and form no part of, the corporation’s charter.” id. at § 4167 (rev. perm. ed. 1966), "[bjy-laws cannot make an act ultra vires....” Id. at § 3436 (rev. perm. ed. 1978).
