Title 15 › CHAPTER 1 — MONOPOLIES AND COMBINATIONS IN RESTRAINT OF TRADE › § 13
Makes it illegal for a business to charge different buyers different prices for the same goods when those sales affect competition, help create a monopoly, or hurt rivals. Price differences are allowed only to cover real cost differences (for making, selling, or delivering items) or when sellers honestly pick their customers and do not try to block competition. The Federal Trade Commission (FTC) can, after investigation and a hearing, set limits on quantity discounts for particular goods; once the FTC sets those limits, larger quantity-based discounts beyond them are not allowed. Sellers may also change prices because of changing market conditions, for example to deal with perishable items, seasonal or obsolete goods, court-ordered distress sales, or a bona fide business closing. If a complaint shows price or service discrimination, the seller must prove a legal reason or justify the practice, or the FTC can order it stopped. A seller can defend by showing it lowered price or matched a competitor’s price in good faith. It is also illegal to pay or accept commissions, discounts, or other value unless the payment is for real services tied to the sale and goes to the other party in the deal or to an agent who is not acting for or controlled by another party to the transaction. Payments to or for a customer for processing, handling, or selling a maker’s products must be offered on the same fair terms to all customers who compete in distributing those products. It is also illegal to give special services or facilities to some buyers on terms not offered to others, or to knowingly cause or accept any prohibited discriminatory price.
