Well, then you're not "waiting out an auction". You're waiting for the next auction. Right?
If you look at a BIN and decide to pass on it, you aren't really waiting out an auction, you're just waiting for a future opportunity to buy that card. Semantics I guess, but you rarely have an either or situation with pre-war cards. I might pass on Nap Lajoie t206 portrait that's listed as a BIN and then buy one a month from now on a BIN from another seller.
