^ i guess it's because they want to be sure they get the item. for example a lot of times when there's a BIN OBO the seller just waits until they get a few offers before picking the best (highest) one. so you may submit an offer that's less than BIN, but there's a chance that soon after someone else comes along with a better offer and then the seller will just give it to them.
or it could be cuz they don't want to wait the 48 hours or whatever to get their offer approved or whatever..who knows. i've never done it, never been that desparate for a bag (yet!)
