Harold Hitz Burton,
Standard Oil Company v. Federal Trade Commission…
“ It is enough to say that Congress did not seek by the Robinson-Patman Act either to abolish competition or so radically to curtail it that a seller would have no substantial right of self-defense against a price raid by a competitor. For example, if a large customer requests his seller to meet a temptingly lower price offered to him by one of his seller's competitors, the seller may well find it essential, as a matter of business survival, to meet that price rather than to lose the customer. ”
