Trade in 5 games for a Nintendo DS or 8 games for either a PSP Starwars pack or Daxter pack.
Each game must be worth 8$ or more in TIV(trade in value), call your local EB to check prices. Deal ends March 31 but some EB games have these promos unadvertised and I've personally got 4 DSes/1 PSP in the past year. They occasionally have deals on consoles too(free 360/100$-200$ off Wii/PS3).
A couple of tips, try looking through local classifieds(craigslist/kijiji) for cheap, high TIV games. Once found a guy selling Sunshine/Melee/Pikmin/Viewitful for 40$, added a game from my collection and I got a DS. If a game isn't worth 8$ or they have too much in stock, call different a location(preferrably new) to see if they'll accept it.
Good luck!
