OK, a little while away as yet but at this price it's got to be worth pre ordering. Best other price i could see was at gameplay using the £5 voucher but still only brings it down to £35 delivered, so i guess this is slightly better, especially for the UK PAL version.
EDIT: Second scan through and i noticed choices are actually selling it brand new delivered for £31.99!! which is pretty good if you wanted to wait a bit closer to release and this voucher offer has run out by then.
Did search and couldn't find it elswhere.
