(adsbygoogle = window.adsbygoogle || []).push({}); In general how much does gamestop give ou for a trade in of a ps3 both phat and slim.

I wouldn't know, I do know that they don't give you that much. You are better off on craigslist or ebay.

Best I've seen was 80 bucks trade in value on a fat when buying a 150 dollar slim.

Other than that, I think 40gigs = 40 bucks. Don't know about the slim.

Selling on the internet is better. Craigslist being the cheapest for the seller.
