As i packed up my order, i remembered this thread. If any of you have any old books/dvds/cds/games (in good condition) you can sell them to one of these companies for a little cash.

I've never used them before but all three companies have good reviews online. You jut enter the barcode/isbn number on their site and it'll tell you how much an item is worth, then when it adds up to £10(2 of the sites) or £15(the 1st site) you agree to the deal, pack up the stuff in a box and print a freepost label. you just take them to a local collect plus location/post office. They check the items against their guidelines and send transfer/chq.
On the three sites, my stuff added up to around £40, of which was stuff that i was trying to sell on ebay but it's no longer worth paying all the fees for. hope this helps someone. x
