If on ps3/xbox you would get approx 拢32. Though you would have to pay the postage to send them away. You then have 拢32 credit, which you can use whenever you feel like it, and there is no postage costs on whatever you purchase. I've used a company called 'GameXchange' many times, and they offer good prices, and a good service..How much would I get for these games if I traded them in?
I really have to start up a store locally that does trade ins, such a killing. People are so happy to trade in their crap for almost nothing instead of selling it on ebay for the same price the store is going to turn around and sell for.
ya probley 50-60 pounds
