Whole Foods is doing away with its smaller, cheaper Whole Foods 365 concept.

Whole Foods CEO John Mackey told workers through an internal email that the company would not open any more of the Whole Foods 365 stores, according to a report in Yahoo Finance. The 12 existing locations — including an Atlanta store that just opened in December — will remain in business.

The 365 concept got its name from the company's in-house brand, 365 Everyday. The stores were smaller than typical Whole Foods locations and contain a pared-down selection.

"As we have been consistently lowering prices in our core Whole Foods Market stores over the past year, the price distinction between the two brands has become less relevant," Mackey said in the internal email.

Whole Foods opened its first 365 location in May 2016 in the Los Angeles area. It since had opened four more California stores, two each in Texas in Georgia and one each in Brooklyn, Oregon and Ohio.
