Costco Wholesale Corporation (COST) Shows How Digitally Enabled Sales Are Outrunning Its Core Business

Costco Wholesale Corporation (NASDAQ:COST) is one of the best e-commerce stocks to buy as global sales hit records. The company is best known for its warehouse-club model, but its online and digitally enabled sales continue to grow at a faster pace than the broader business. On June 3, Costco reported net sales of $24.01 billion for the retail month of May, the four weeks ended May 31, 2026, up 14.5% from $20.97 billion a year earlier. For the first 39 weeks of the fiscal year, net sales rose 10.0% year-over-year to $221.19 billion.

The e-commerce angle showed up clearly in the same update. Costco’s total comparable sales increased 12.5% for the four-week May period and 8.3% for the first 39 weeks, while digitally enabled comparable sales rose 21.1% and 21.6%, respectively. Excluding gasoline-price and foreign-exchange impacts, digitally enabled comparable sales still grew 20.9% for the month and 21.1% for the 39-week period. Costco also has a broad international footprint, operating 931 warehouses and e-commerce sites in markets including the U.S., Canada, the U.K., Mexico, Korea, Taiwan, Japan, Australia, and China.
