Ipad Air instore at John Lewis 32Gb was £249. These are open box returns so still brand new, mine still had protective screen cover etc, still have 2 year guarantee this was confirmed by staff member and at till.
Had a few in Buchanan Galleries, also had 16gb Air for £269 (seemed strange).
Also had Samsung galaxy tab pro 8.4 for £149, worth a visit if you can get instore.
will get an image uploaded of proof
