Spar’s own-label discount range S Budget has smashed expectations and hit £2m in sales for the five Spar wholesalers since its September launch.

The S Budget energy drink (250ml, rsp: 42p) was a particular success, with half a million cans sold since its launch, a spokeswoman said. Fresh chicken and mature white Cheddar have boosted overall fresh foods sales in Spar stores.

“Our Spar retailers’ overall margin is now much higher than if they were only selling branded lines,” said UK brand director Susan Darbyshire.
