Been looking for a Note at the right price for a couple of months now. This is the cheapest price I've seen from any "reputable" UK-based retailer for a sim-free unlocked Galaxy Note. Next cheapest I could find was Amazon and Play.com at about £385
This is only for the white model. The Carbon Blue device comes in at £379.
And as pointed out below, you should qualify for 5% Quidco too!
