I also agree. The good deals are short lived. If I am bidding on an item, I will 'watch' other BIN items that are fairly priced from the same seller. If I win the main item I often pick up a few other incidental items if shipping is combined. I do the BIN for the second items rather than delay waiting on the auction to end and discover I get beat anyway (and wasting time on the original delivery).

BIN items are often overpriced BUT so are the auctions when uninformed buyers or shills run up the price.
