ST. LOUIS — Discount grocery chain Save A Lot has unveiled plans to update and rebrand one-third of its stores this year as it continues its transition to a wholesale model.

The new store design will be introduced to all 1,000 of its stores in 32 states by 2024, the company said in announcing the plan.

Save a Lot said it is working with the stores’ “independent license owners” on the modernization campaign. Save A Lot serves as a licensor and wholesale partner to more than 200 independent owners and operators, which customize their assortments according to local conditions.

The new store design represents “a contemporary evolution of the brand inspired by customer and employee feedback,” according to Save A Lot.

The result will be “a lighter, brighter and easier-to-shop footprint that includes new decor and an enhanced shopping ­environment.”

Each store will feature an assortment of regional products, including a variety of localized product brands curated to resonate with customers in the local community, according to the ­announcement.

Save A Lot said it is pleased with an initial round of upgrades that modernized the look and shopper experience at stores in the Tampa, Fla.; St. Louis; and Denver markets.

“As we continue to focus on becoming the brand of choice for our customers and a go-to source in our local communities, it was important that our logo, stores and marketing reflected and reinforced our mission of providing quality products at budget-friendly costs that consistently exceed the expectations of our customers,” said chief executive officer Kenneth McGrath. “This refresh positively supports our efforts to further evolve and gain new shoppers, retain our current shoppers and increase our basket size. We’re particularly pleased to collaborate and co-invest with so many of our independent retail partners to make this possible.”

Earlier this year, Save A Lot said it was selling some 300 corporate-owned stores to existing retail partners, which will continue to run the stores as Save A Lot outlets.

Fifty-one of the stores are in the Tampa metro area and were sold to Fresh Encounter Inc., a Findlay, Ohio-based supermarket management company and a Save A Lot retail partner, which continues to operate the Tampa-area stores under the Save A Lot banner.

Save A Lot also said it would continue to own and operate 21 stores in the St. Louis area, using the locations to develop and introduce innovations that can benefit its retail partners across the United States.

Among the brand revitalization efforts emphasized in this week’s announcement is an expansion of digital marketing efforts, including the 99 Days of Summer campaign that was launched in May and runs through September 6. The marketing program aims to provide value-saving digital offers to customers, with daily deals, weekly digital coupons and summer sweepstakes prizes.

Save A Lot, one of the largest discount grocery store chains in the U.S., is also upgrading its technology, deploying an Aruba ESP (Edge Services Platform) network in its stores, headquarters and other facilities for a more modern, mobile- and cloud-first environment.
