Gamestop extra 30% on trade-ins if you pre-order GTAV

I just traded in my 3DS and 30-40 PS3 games at Gamestop, and I didn't even know about this deal. It ended up getting me an extra $80 in credit. So now I've got GTAV and strategy guide paid off, I've got my PS4 completely paid off, and I've got $140 in credit on my Powerup card toward next gen games :) Not to mention when the PS4 comes out I'll trade in my PS3 and the 10 games I've got left. So it's like next gen is going to be almost free :D

Its better to start early and pay stuff off. Because when everything comes out, it's going to be alot of money to spend at once and might feel overwhelming.
