Tesco is altering its offer to refund double the difference on products bought more cheaply at Asda to refund only the difference.
According to the retailer, the double the difference pledge has given rise to a cottage industry of savvy and determined people, who identify products which are on short-term promotion in Asda then buy them at Tesco, claim the coupons through Price Check, buy more of the same products with the coupons and go on recycling coupons in this way just to make money.
A Tesco spokesperson said: “Price Check has given our customers confidence in our prices and transparency. But some people have misused the scheme to cash in. So we have taken this step to protect Price Check for the majority of our customers.”
