Hi all, Argos (in the UK) have started stocking iPads now. my girlfriend's offered to get me one for xmas so looking at the 16gb wifi version. Now, Argos has a £5 off every £100 gift vouchers bought.. So i was thinking buy 4 lots of £100 gift vouchers and get £20 off.. will this work? this should bring the price down to £409 for the iPad has anyone taken advantage of this like this?
