I've cancelled my game order and ordered the tesco one - saving me over £60! I work weekends so won't be playing it till the Monday so the fact it won't be here on the Friday doesn't really bother me.
Game are a giggle though, you can't cancel your order online so I joined one of those webchat efforts in which I was told it was cancelled, then it was not, then the games were cancelled but the console was not, then it was, then it has been sent to the warehouse so it couldn't be cancelled - I said jog on! I haven't paid for it therefore I don't own it therefore I can cancel it all day long!
Anyway I'm receiving an e-mail apparently shortly confirming my full cancellation. We will see!
