Nikon D90 Kit with the 18-100 VR Lens, which for a stock lens gives extremely good results! I purchased this camera from Dixons Tax Free a couple of weeks ago at £680 and knew I was getting a bargain then, but now I can not believe it's now £621? The cheapest I can find it anywhere else at the moment is £660.
And before any one says that you'll have to pay the tax when you return to the UK, - I have purchased many items from Dixons Tax Free in the past and have never needed to pay Tax upon my return!
The only problem with this deal is that you'll need to be flying somewhere (albeit any where inc UK), although maybe this would be a good reason for a much-needed holiday!
