I get if the NTSC versions is diffrent.. ie assassins creed boxsets, the fallout one has a diffrent box to ours.
but call of duty and mass effect? there's no diffrence between the 2?
Obviously no one wants to argue mate
but if you genuinely think your items are worth this sort of cash and your not just being slightly OTT then good luck.
Seriously though.. call of duty you could actually buy 2/3 pal versions(identical) and our free "limited" cell came in a presentation folder, with a dlc cd and avatar card.
