Sales at Costco have been going on for about two months, and the company’s sales of items from clothing to televisions and electronics have been strong.
Costco said Friday that it has sold nearly 5 million items since the end of August, the best quarterly performance since 2012.
The company said that it sold 2.2 million items through Oct. 31, which is a 1.5 percent increase over the same period last year.
That’s a big increase, especially given the fact that the company has been hit by a spate of supply disruptions.
In September, the company had to shut down its U.S. distribution center and move its U, European and Asian markets out of the country.
The next month, the plant closed.
The U.K. announced it was cutting the company of its entire logistics operations by the end to January.
And a month later, Amazon said it would pull out of its U., European and Latin America distribution center.
The closures are part of a wider slowdown in the U.N. Food and Agriculture Organization’s (FAO) forecasts for global food and agriculture demand, as food and farm markets continue to tighten.
Costco’s stock dropped 2.7 percent in after-hours trading Friday, while the S&P 500 index rose 2.1 percent.
That was the second-largest drop for the company in the past 24 hours.
Costco expects to see a 2 percent to 3 percent decline in net income for the third quarter, which ends in May.
The stock has lost about 2 percent since it closed the year with a profit of $4.5 billion.
Costco is the second big retailer to announce a sale.
Target announced in March that it was closing a warehouse in Iowa and closing stores across the country, in addition to its national distribution center in Colorado Springs.
The retailer said the decision was made to focus on the U and European markets.
It said it will spend about $1 billion to upgrade its U and Europe warehouses.
