I just ordered this on blu ray for £30 using a £15 off voucher.
I went via a cashback site and got 8% of the £45
Its for new customers but I am not new :) and i got it today and they stuck the £15 back on my visa card.
I used code ZZ437 and free postage XV002
in the end i pay £27 for it. Thats 50% off amazon price etc!!
