thing Coz thought another. Coz never made a bona fide offer. I claim offering to pay him a $100 and he shipping constitutes "offer and acceptance." He claims $100100 is a catalog number, not a price, from which a price is to be inferred. Fortunately, either way is a trifle.
Having dealt with contracts for many years I should know that a quote is not offer. But in the world of petty retail the terms tend to used interchangeably and don't form the basis of a compelling argument, except perhaps in court.
