as a buyer I don't like this.
for one you will not get a chance to pay with a credit card should you have a balance. and i'd be wiling to bet they will take it from your bank account before using your credit card since as we all know, ePal is evil.
I don't want to have to remember if I have any auctions ending as a buyer when I am standing in line at the grocery store getting ready to pay with my Paypal debit card.
I have so few unpaid items it is a non issue for me. I'll tell you one thing though, I'd rether have an unpaid item than a return.
