Costco has issued a warning to shoppers that purchase limits might be in place for certain items.

The warehouse store did this at the start of the pandemic, when people panicked and hoarded supplies like toilet paper and paper towels.

Now that coronavirus cases are increasing again, that’s happening again.

The Centers for Disease Control reports as of September 1, the 7-day average of COVID-19 cases in the United States was up almost three percent from the previous 7-day average. That average is more than 107% the peak seen on July 20, 2020.

Pictures from social media show empty shelves at Costco.
