I've been looking into buying this camera for a while, and Amazon seem to be doing it for the cheapest price.
There is a £60 cashback deal on which means you can claim the money back after you've bought it for £744.60 and effectively pay £684.60 for it.
See here for Detailshttp://www.nikon.co.uk/sites/cashback/offers-spring.html
The cashback deal offer ends today (30th April 2010).
Jacobs: £791.99 (£731.99 after cashback).
Jessops: £779 (£719 after cashback).
Dixons: £799 (£739 after cashback).
