Yrah. Sign up to it and check before any biggish purchase. It directs you to the retailer so you deal direct. Costs you no more than going direct. They get a referral fee which they share with you. Here’s some of mine. There’s another one called Quidco. Same principle. You only get it on new purchases (insurance, utilities, breakdown cover etc) not renewals. When I come to renewal time, I buy again in Mrs Motties name.

Google it.
