All my items are BIN. There is no excuse, imo, to not pay at the time of purchase.

Unless, of course, the buyer kills themself because they were driving at the time they bought the item.

Don't think required if you open unpaid item case, and buyer desn't pay after that, you get final sale value fees back, so what does a seller loose.

Ebaysays  if you lodge an unpaid item claim, and a Ebayer gets 2 of them on their account, they can loose thier account.

I had issues just recently on one item,  Lets face it, there are Morons in real world and there is on Ebay. Just socieity.

As for charging bidders for not paying, getting into a bit of a grey area, as when or what would critera be.

As was mentioned earlier in this thread a cart system would eliminate a lot of angst as the item would not be removed from viewing and therefore still available to purchase by someone else if the first buyer did not follow through with payment then and there.
