Jacobs have started doing £100 instant rebates off the Nikon D7000 Body only. You don't need to send off the these, the rebate is taken off at the till so you only pay £849.
They are still prices at £949 online though so if you want the additional £100 off then you'll have to find a store.
There is a poster in the window of the sheffield store but I don't see why it wouldn't be nationwide. Probably best to call your local branch before popping in.http://www.jacobsdigital.co.uk/findus.aspx
