I would wait for it to be closer to MW2's release, as gamestop often has specials where you can trade in games for their sequals. By doing this, you would get more credit than if you were to trade it in now. Anyways, I would believe that you would get around 25-30$ for both the game and the guide to gamestop.How much Would i get For COD: 4 MW With Guide?
You will get about $20-$35 for it depending on the system it is for. A lot less at gamestop unless you wait until the game gets closer to release. At that point gamestop has many deals which would allow you to get more and maybe do something similar to a trade-in ,but only if it is a console game. They no longer accept PC titles.
