Nope, not sure where you were looking as the cheapest MBP is £1249 inc VAT on this website and the same price at Apple. Although there are better deals out there if you can bang it on a credit card as you can then pay up front.
Their prices appear to be about 20% higher than anywhere else? Prices shown appear the same, but VAT is not included and only shows when you go to your shopping basket!
Or EBay and the PayPal deal? ;)
Why not shop for the best price wherever it's cheapest then putting it on a 0% for 22 months Halifax CC?
Nice. In-store only though which is a shame
