GAME Trade-In - How much would I get?

I need to come up with £70 by Monday, So im trading in some games I dont really play much.

Mario & Sonic At The Olympic Games
Smackdown vs Raw 2008
SSX Blur
Eledee's
Excite Truck
Mario Party 8

I was kinda' hoping to get £10 for each seeing as they are in mint condition and each game has been out for less than a year.

I think youll get like 40/50quid

Thats about how much I need as my mum is giving me £15 anyway

you might get £70 (including the £15 ur mums giving you).
for the games alone, you will probs get about £50

£35 - £50 for the games I'd say. Try Gamestation as well, make sure you get the best deal.
