COSKIN CKY-5650AT Digital photo frame is £67 + delivery from Pixmania.co.uk (was £100)
I havent included the delivery charge in the title because you have a wide range of options for delivery. Delivery is FREE if you have a PixCard (+ further discounts), around £4.00 if you are willing to collect from their warehouse in London.
This is the cheapest price I could find for a Digital Photo Frame. With the price of SD card falling down, there is no better time to grab this Digital Phone Frame. Go through Quidco for 3% cashback.
