I purchased a brand new Canon EOS 600D Digital SLR with 18-55mm Zoom Lens from the Dixons tax free shop on Monday night for £582 which is over £100 cheaper than I can find anywhere else. This was from the Dixons Tax Free store at Manchester Airport T1
This includes the lense and they even did a deal on a case!
This is a bargain for anyone traveling through the airport (I assume other airport shops have the same deal) or if you have friends using it.
PRICE UPDATE _ HEATHROW T4 @ 18/05/2011 = £636.
