. . . if consideration (payment sent and accepted) is made, hasn't a binding and enforcable deal been made (whether item has shipped or not is irrelevent)?

I'm not the buyer either, and have lost out on a much needed autograph due to auction ending early, but I'd be a tad upset if I had made payment at an agree upon price, only to have the seller reconsider after accepting payment. Wouldn't you be miffed if the seller pulled that on you?

Just my position.
