The $1 million dollar one and the $15,000 one are fake. Look at the bid history and see that the last bunch of bidders that are the highest were not registered users. Therefore the person who listed it was trying to drive the price up himself. Noone in the world would pay 1 mil for a ps3 or even 15 grand.....If you do, you are an absolute moron.
He'll just relist it on ebay after that. When you relist it, ebay waives the final value fee. He figures, if someone is dumb enough to pay that, fine, he'll be rich, but if not, he'll relist it, won't have to pay the final value fee, and then sell it for a realistic price. Hey, it was worth a try (at least to him)
