So i'm thinking of trading in Soul Calibur 4 when i buy Dead Space, just cos £40 is a little too much to be spending at the moment (student-ness, and replacing my lost Creative Zen).

Does anyone know where the best place in the UK is to trade it in, and how much i'd get for it? I get the feeling it's a popular game to be traded in so i'm thinking £15 would be a good price maybe.

Gamestation, Game, and Blockbuster seem to be the main options, but i'd feel a bit sick giving them MORE money, but eBay's pretty dead for soul calibur 4 and i'm hoping they'd give me more in store credit to buy dead space with.
