I sell a ton of stuff on eBay (finished glass pieces as well as glass supplies) and I'm always amazed at the prices people push them to when they get in a bidding war. I have one book I sell all the time and I plainly state that the bidding starts at $9.45 but that I have it in my eBay store for $13.95 yet the auctions routinely end at far more. The best so far was someone paying $44 for it. People are definitely nuts. When I'm buying on eBay I always check the eBay store and, if the seller has another website, alternate sites as well to make sure I'm not bidding more than I would pay otherwise.
