Costco Wholesale Corp.’s September sales rose 15.8% to $19.5 billion, from $16.8 billion a year ago, the retailer said late Wednesday.
said its same-store sales increased 14.3%, with e-commerce sales ticking 10.6% higher.
That September sales increase compares with an increase of 16.6% for July sales and 16.2% for August sales.
Costco shares edged higher in the extended session Wednesday after ending the regular trading day up 0.7%.
The retailer said last week it was back at limiting purchases of toilet paper, some cleaning supplies and other sought-after items thanks to an uptick in demand related to the delta variant.
It has been experiencing the same supply-chain shortage and delays plaguing other companies, it said.
The company reported rising fiscal fourth-quarter sales and profit.
While higher demand for its bulk buys have helped the retailer during the pandemic, costs, particularly those related to wages and public-health requirements, have also escalated.
Costco shares have gained about 19% this year, compared with an advance of around 16% for the S&P 500 index.
