Plaintiff’s claim is based on defendant’s alleged breach of the following portion of Exhibit B:
“Witnesseth, that the seller agrees to furnish the buyer stone F.O.B. the quarry site at Cycle, North Carolina at the following prices:
Crusher run stone @ $1.25 per ton
Clean concrete stone @ 1.60 per ton
No. 11 stone @ 2.00 per ton
It is mutually agreed that the seller of this stone will keep someone at Cycle, North Carolina, at least five days a week to weigh and load the stone the buyer should need.
J. E. Dooley & Son, Inc., agree that they will not sell any stone to anyone other than the State Highway Commission for prices less than the following from the Cycle Quarry:
Crusher run stone $1.50 per ton
Clean Concrete stone 1.80 per ton
No. 11 stone 2.00 per ton
The above restrictions shall apply only to an area of an eight mile radius of Elkin, North Carolina, and shall apply for a period of ten years from the date of this contract.”
Defendant assigns as error the court’s conclusion of law that the two agreements (Exhibits A and B) between the plaintiff and Dooley were valid contracts and at all times complained of, were binding on the defendant, at least with respect to the specified prices to plaintiff for stone and the obligation of defendant to sell stone to plaintiff at such prices.
Defendant contends “ . . . that each of these contracts was illegal and void on its face and that the Plaintiff may not main*698tain an action for breach of these contracts in order to recover the difference between the specified prices at which he was to be sold stone under the contracts and the prices he was charged when the Defendant became aware that the contracts were illegal.”
The question thus presented for our determination is whether the contract sued on (Exhibit B) is in fact “illegal and void on its face.”
G.S. 75-5 (b) provides:
“In addition to the other acts declared unlawful by this chapter, it is unlawful for any person directly or indirectly to do, or to have any contract express or knowingly implied to do, any of the following acts:
(5) While engaged in dealing in goods within this State, at a place where there is competition, to sell such goods at a price lower than is charged by such person for the same thing at another place, when there is not good and sufficient reason on account of transportation or the expense of doing business for charging less at the one place than at the other, or to give away such goods, with a view to injuring the business of another.”
The Robinson-Patman Act, 15 U.S.C.A. o á. pa o xn CO T“l
“It shall be unlawful for any person engaged m commerce, in the course of such commerce, either directly or indirectly, to discriminate in price between different purchasers of commodities of like grade and quality, where either or any of the purchases involved in such discrimination are in commerce, where such commodities are sold for use, consumption, or resale within the United States or any Territory thereof or the District of Columbia or any insular possession or other place under the jurisdiction of the United States, and where the effect of such discrimination may be substantially to lessen competition or tend to create a monopoly in any line of commerce, or to injure, destroy, or prevent competition with any person who either grants or knowingly receives the benefit of such discrimination, or with customers of either of them.”
 It seems clear that the contract on which plaintiff bases his action violates both state and federal statutes.
*699The contract contains discriminatory and preferential prices which, if enforced, could have had the deleterious and illegal effect of harming or destroying plaintiff’s competition. Such is clearly forbidden by G.S. 75-5 (b) (5) and the Robinson-Patman Act, 15 U.S.C.A. § 13 (A).
With the exception of “#11 stone” the rates to be charged to plaintiff under the contract were at least $.20 per ton less than that charged to plaintiff’s competitors. Plaintiff’s claim and the court’s findings and conclusions amply illustrate the significance of these preferential prices. Had defendant honored the provisions of these illegal contracts, plaintiff would have benefited to the extent of $25,231.57 over his competitors.
The discriminatory pricing cannot be justified under the exception contained in G.S. 75-5 (b)(5) “ ... on account of transportation ...” since the stone was to be furnished to plaintiff “ . . . F.O.B. the quarry site at Cycle, North Carolina. ...”
The contract relied upon is clearly illegal and unenforceable.
The trial court’s findings that the agreements were supported by consideration has no legal significance in determining whether the agreements were in violation of the antitrust laws.
It is the rule in North Carolina that in the case of an illegal contract the courts will leave the parties as it finds them and will do nothing to enforce the agreement. Marshall v. Dicks, 175 N.C. 38, 94 S.E. 514 (1917); Florsheim Shoe Co. v. Leader Department Store, 212 N.C. 75, 193 S.E. 9 (1937). The court will not adjudge liability against a defendant for refusing to do that which the law makes it illegal for him to do. Hanauer v. Doane, 12 Wall. 342, 20 L.Ed. 439 (1871); Continental Wall Paper Company v. Louis Voight & Sons Co., 212 U.S. 227, 29 S.Ct. 280, 53 L.Ed. 486 (1908).
 It is clear that an agreement that violates the antitrust laws is void and unenforceable and that the illegality of a contract on the grounds that it violates the antitrust laws is a defense against a suit for damages. Standard Fashion Company v. Grant, 165 N.C. 453, 81 S.E. 606 (1914); Florsheim Shoe Co. v. Leader Department Store, supra; Arey v. Lemons, 232 N.C. 531, 536, 61 S.E. 2d 596 (1950); Electronics Co. v. Radio Corp., 244 N.C. 114, 92 S.E. 2d 664 (1956).
*700In the last cited case, Bobbitt, J., now C.J., stated, “If the contract is illegal, either at common law or by reason of statutory provisions relating to monopolies and trusts, G.S. 75-1 et seq., plaintiff cannot recover damages for breach thereof.”
