The independent forecourt retailer sector could be supporting supermarket businesses to the tune of £10 million a year by participating in loyalty card schemes, claims Ramsay MacDonald, retail director of Certas Energy.

In a New Year message to retailers nationwide, he is trying to encourage them to think hard and really look at the nuts and bolts of the business before taking the "devil you know" approach to signing up with a major brand.

"With cards like Nectar and Tesco Clubcard, retailers are paying without getting much in return," he said. "If they were getting access to the CRM data information about their own customers it would be worth it, but they’re not.

"They’re paying for the points come what may, whether they’re given out to customers or not, and their customers don’t redeem points in their business."
