[quote name='suko_32']Or I mean there's a possible non-paying bidder for one of my auctions, if the person eventually doesn't pay, do i get all my money back?[/quote]
if you have a non-paying bidder, you have to follow the necessary steps. just search "non-paying bidder" in ebay's help section and you will find it. basically, i think you have to wait about a week to file a non-paying bidder report, and then if the person still doesn't pay after another week to ten days, you file a final value fee refund claim, where you will be refunded the final value fee, but not the insertion fee.
you should, however, have the ability to relist the item for free.
