Before people start shouting the odds saying its a waste of time, i posted it because it's a way of getting free money.
Currently play.com are selling rayman raving rabbids 2 on Nintendo wii for £17.99, you can use the 5% code and 4% Quidco get it to £16.38
Once bought if you take it into game and ask the trade in price, they will say £25. Ask them to print it on a reciept then take it into gamestation show them the reciept. Not only will they match the price but will give you a £1 Extra. So will have a £26 pound credit voucher for gamestation when you only spent £16.
This may seem like alot of effort but it's up to you if you want to make yourself a bit of free money.
You may ask how i know you get £25 pounds in game. Well here is the up to date trade in guide. http://www.game.co.uk/lowdown.aspx?lid=7808&cm_sp=consoles-_-topnav-_-tradein
This game on it's own is not a bad price either if you want it to keep.
