I personally don't like the way Jessops present some of the products on their site that have a promotion, where they state the price after cashback first (with price you pay today in red). Then other items the red text is for the amount you save:
same price with Jessops and Amazon.
For anyone who is curious like I was (from the Nikon promotion T&Cs): Nikon UK Ltd cannot accept claims against products purchased from eBay (whether listed as new or used). Purchases from Amazon will only be accepted when made directly from amazon.co.uk and not from 3rd party sellers on Amazon Marketplace, whether fulfilled by Amazon or not.
