Philippine supermarket chain Puregold Price Club is finding growth as a supplier to small-scale retailers.

Puregold’s number one customers are owners of sari-sari stores – mom-and-pop stores found in almost every corner of the Philippines. These stores, said to be totaling more than 700,000, sell consumer staples, from snacks to toiletries.

Puregold Price Club stocks candies, condiments and other items in small portions convenient for resale. A membership system has further solidified the chain’s position as a supplier to sari-sari stores.

Puregold plans to expand to 500 stores, Chairman Lucio Co has said.

The company has brought its business to Mindanao and other outlying areas, while acquiring supermarkets across the country. In 2015, it began operating convenience stores through a tie-up with Japan’s Lawson.

The first Puregold supermarket opened in 1998 and grew rapidly to 267 sites at the end of September 2015, with sales of 84.8 billion pesos ($1.8 billion) in the year ended December 2014.
