Independent grocer Haggen and wholesale grocery distributor Unified Grocers have extended their supply partnership for an additional five years.

Commerce, Calif.-based Unified Grocers took over the original supply agreement when it acquired Seattle-based Associated Grocers in 2007, according to a news release.

“The new agreement will provide additional efficiencies for both companies while providing consistent execution with access to the greatest variety of products for Haggen’s customers,” Leon Bergmann, Unified’s executive vice president of sales and procurement, said in the release.

The agreement’s flexibility and structure also should complement Bellingham, Wash.-based Haggen Northwest Fresh’s go-to-market strategy, according to the release.

“We have renewed our partnership and are looking forward to building upon the strong foundation we’ve already established,” Clement Stevens, Haggen’s senior vice president of merchandising and marketing, said in the release. “We’re confident that Haggen’s vendor partners — and ultimately, our customers — will benefit from the ever-growing selection of quality products.”
