Good news for you, if you own a PlayStation 3, or are interested in purchasing a PlayStation Portable.

PlayStation LifeStyle reports that as you can see in the above image, GameStop has a coupon for 20 percent off of used PS3 games, up to three. Of course, that's only good if you live in the United States, Puerto Rico, or Guam.

The other deal, as Joystiq tells it, is that the purchase of a new PlayStation Portable will net you a free copy of Loco Roco 2 or God of War: Chains of Olympus. They note:

"Our local GameStop stated that the offer was only good for the core system, though it looked like the discount was being applied when we put a Dissidia bundle into our cart on GameStop.com (attempt at your own risk)."

Both deals are only valid until this Thursday, May 21st, so if you're going to act, you'd better make it snappy.
