I'm sure you're all aware of the Signature PSP lineup by now, but did you know Sony teamed up with Coca Cola to manufacture 1,300 Hot Shots Golf: Coca Cola Special Edition PSP bundles in Japan last year? The bundled Hot Shots game, which Coca Cola gave away in contests, was basically a big commercial for the company as it featured Coca Cola advertising, clothing and even bottle-shaped golf clubs.
Unfortunately, the contests are all over and you can't win one anymore. However, if you have about $660 burning a hole in your pocket, the bundle can be all yours via an eBay auction here. You even get the prize letter from Coca Cola to make you feel like you've won something.
