I'm not that worried about it, I guess. I've only had that happen one time. I claimed an item, and posted a PIF and the guy I claimed the item off of refused to send me the stuff b/c he claimed he never rec'd the item he had claimed. Ticked me off a bit, but it wasn't that big of a deal. At most I was out a few buck for shipping on the item I PIF'd. 'Can't complain, as I've posted a couple items that never got picked up. It's all good in the end. Not that big a deal really.
