Ford, Dodge, and Chevy are competitors of each other in the auto industry. Ford buys 800 carburetors at the normal price of $400. Dodge then buys another 800 carburetors at the normal price of $400 in the same year. Also in the same year, but after Ford and Dodge, Chevy buys 800 carburetors but at a price of $300. Ford and Dodge discover Chevy's reduced price and file suit against Holley under Section 2 of the Clayton Act for price discrimination. (Assume that all other elements for section 2 of the Clayton Act are met.) Holley's defense is:
