Boots currently have most of their digital frames on offer. The best buy to me was the Kodak SV711 7in reduced to £44.99 (£5 cheaper than argos).
They also have the SV811 reduced to £69.99 among others.
The Kodak ones mentioned have sold out online so instore only. They do have the new models online though, along with a few others.
With a lot of stores doing the extra points night tonight, thought it might be worth a mention.
