The Right Choice own label range, which sits alongside its Heritage brand, is being rolled out to wholesale members. Right Choice is being extended across all grocery lines, with many packs price-marked.
At the same time, Nisa-Today's has signed up a Manchester-based non-food supplier, 151 Products, to extend its non food lines to include car care, stationery, cookware and also DIY products.
Nisa-Today's said that the products would offer a margin of 35% to 50%.
Retailers can choose the lines they want, based on local consumer purchasing habits.
Separately, the first Today's Extra store to be supplied by Today's Group wholesalers is scheduled for launch in Cottingham Road, Hull, on June 1.
The event would coincide with National Independents' Day, co-ordinated by the Federation of Wholesale Distributors to promote independent retailers.
Extra is Nisa-Today's largest shop format, the others are Local and Express.
The 3,600 sq ft shop is affiliated to Today's Group member Dee Bee's Cash & Carry, which has been heavily involved in its redesign.
