I've been researching the price of the Canon EOS 400D for a few days before buying one and the best price seemed to be around the mid £470's from online stores including delivery.
However, today Jessops have the 400D (Silver) for £469.99 online and instore and this is the best price anywhere. I went in at 3pm today and the manager knew nothing about it until he checked and confirmed it was an offer that started this afternoon.
Also, inside this months Photography Monthly there is a Jessops voucher (at the back) that will allow Jessops to price match any item listed in that magazine (not the online prices but the printed price only) but all the online suppliers have adverts in there with their online prices listed so this counts. I got an additional lens that retails in Jessops for £199.99 for £78.99. The manager said they'll honour any price shown in the magazine as long as you present the actual voucher in store. The voucher is valid until the end of April.
Hope this helps someone...
