Great chain of explanation for what seems like irrational or offensive ebay seller pricing. I've always wondered about such behavior. Two things I've noticed; 1) Sellers may start out with a high bid price, relist at a lower bid, then iteratively relist at a lower buy it now price, patiently fishing for a buyer; 2) List a well known, desirable product above market value (buy it now), then issue a private offer to watchers at or slightly below MV that gets snapped up within 24 hours.

Both of the above tactics seem pretty successful, judging at least by the fact that I and others have fallen for it. In both cases you may be motivated by the idea that "the other guy" will get it before you do. Good psychology!
