More than 200 Spar retailers have signed up to AF Blakemore’s Retail Partners Plus (RPS) scheme since its launch last year.

Under the scheme, members are asked to buy 95% of their stock through the wholesaler and adopt planograms in exchange for better terms.

RPS members outperformed retailers that were not part of the scheme by four percentage points on a like-for-like basis, said trading director Mike Boardman.
