After the $100 and tax, these prices are insane. If you can get the game on craigslist for the same price, you have more time to see it and inspect it. You can talk to the owner and get details you can't from an auction, people go nuts at auctions.
Even without tax and the fee, these prices are crazy high for an auction. An auction price should be a deal price 20% off minimum. Those days are over.
