Gamestop are running an offer at the minute were if you trade in 3 games from a quite large list and add 3 quid you get any brand new game. Now these deals usually suck and this one does have some ridiculous titles to trade in, but there are some very good bargains.
For example i traded in:
Fallout 3 (normal edition), Gears of war 2, lego harry potter and I got LA Noire.
forza 3, Call of Juarez: Bound In Blood, gta IV and i got lego Pirates
I have picked up most of these games for a fiver using this site so i have paid about 18 quid for these brand new games. It might not appeal to everyone but i got a bargain and i think a load of you out there can as well.
The list is off the gamestop.ie website and it gives the prices in euros, but it is the same in pounds as well.
