The eagle eyes at JustPushStart.com (linked above) spotted a limited time GameStop promotion on trade-ins today, which offers up to $200 in store credit on used PS3 entertainment systems.
For those who aren't worried about losing OtherOS functionality, you can now trade in your old PlayStation 3 console for $200 credit towards a less-shiny new PS3 Slim model... just be sure to do so before the offer ends on July 18, 2010.
To quote: "By trading in a PS3 with one controller and the AV cables, GameStop will offer you a big $200 bucks (store credit). It doesn't matter if you have the fat or the slim PS3s. The store will gladly give you a store credit of $200 regardless of what model. Just make sure it works though!
Trading it towards something else is a great idea for this deal. Don't miss it! It only last until July 18th."
