For example, the price of a Canon 50D right now is cheapest at Dixons (with a £25 voucher) at £829.99 (with postage). But if you were to check the price of Jacobs (but don't click the link, affiliates and all that), you'll see that it is £849.99 with free postage. Now visit quidco, and see that Jacobs give you 3.5% back. So that works out to be £820.24 after rebate (or £825.24 if you haven't earned your £5 subs with quidco). So in the long run, save more money!
