An independent retailer has asked wholesaler Smiths News to explain why a supermarket is apparently earning an extra 2.5% over the industry standard margin for selling partworks.

Southampton newsagent Jon Dudley has raised concerns after he was mistakenly left with Tesco delivery paperwork showing the retail giant was being paid a 25% margin on two collections – above  the 22.5% paid to others.

Publishers De Agostini and Eaglemoss and distributor Comag said terms were negotiated between wholesaler Smiths News and the retailer.

Mr Dudley said that indies deserved better terms for their work in establishing sales and building repeat business through shop saves.

“I was very surprised and would like to know exactly why Tesco is being paid more, given that I do not believe it puts in the same work to build and retain customers,” he said.
