If you’re reading this site, you’re probably a pretty wise shopper. You like a bargain and you don’t do your weekly grocery shop at your nearest motorway service station. You probably also save yourself extra £££s by using a cashback site whenever you shop online.

If you don’t, new research has suggested that you could be saving an average of £123 a year and that Britons on the whole are missing out on £3.3 billion in cashback payments every year from sites like Quidco, Topcashback and Cashbackkings. The survey, carried out on behalf of Kelkoo, has shown that two out of five online shoppers have never used a cashback site and a quarter of those said they had never even heard of them.

Bruce Fair, managing director of Kelkoo UK quacked: “It’s remarkable that these untapped millions go unclaimed because online shoppers don’t take advantage of cashback services. In many households, money is tight at the moment, so shoppers could really be benefiting from the additional money by ensuring that they are making the right decisions in order to get the best deals on their purchases.”

He went on to add: “£123 a year is a lot you know. You could buy almost 200 Wispa Golds with that, or 25 budget-priced kettles or six Union Jack boob tubes (pictured). You’d have to be crazy to knock that back.”

Hang on, he didn’t say that last part; it was actually our latest work experience berk, Maths Mike. Thanks Maths.
