Whole Foods announced last month that it had a record first quarter, with sales reaching $4.7 billion. That sales figure amounts to average weekly sales per store of $724,000, or sales per gross square foot of nearly $1,000.

Co-CEO Walter Robb said the strong numbers were due to its customers’ positive response to the company’s strategic initiatives along with improving consumer confidence. The strategic initiatives cited include the “values matter” television and print campaign, the 15-city partnership with Instacart, digital technologies like Apple Pay, and a test of lower pricing in select markets.

Whole Foods also said it expects to open between 38 and 42 stores this year, including relocations.
