So you're one of the people who buy from that outfit. I've always wondered.
When YOU look at that listing, you see the Buyer info? Could you be looking at a previous or later listing? That outfit has been on ebay forever so I doubt they are trying to scam You. Since ebay and PP take their quart of blood based on final sales price I see no benefit whatsoever in upping the price After auction end. I see no way of doing it either unless it's some feature of the 'ebay store'. Doesn't make much sense.
