In Septembers 'Photography Monthly magazine' there is a voucher within a full page advertisment which you can take into any store and Jessops will price match and camera or lens in the magazine (Including warehouse express!!!!).
This only applies to cameras and lenses.
I have just purchased a £850 lens (Jessops instore price) for £699 (warehouse express price) using this voucher.
In store only and the magazine is out now.
