******* I would be very careful. I have a friend who works for the online cat. He thinks that they are purposely letting silly voucher codes work. Example ZG674 at littlewoods which is 50 pounds off. So buy a game for 52.00 and after voucher thats 2.00 for COD WAW!!!! But what they will do is let you accept/ Refund the discount so your happy on your statement and then after xmas 14 days money back or whatever they will check everyone and take your money!! I have spoken to citizens advice and trading standards and they can do that. Also says in their terms and conditions. I am just sending my items back now. Some of you may be lucky and slip under. But its a nasty risk if it goes pear shape.
Its cheeky but they will be happy everyone is buying from them.
