If you’ve been in a grocery store during the coronavirus quarantine, you’ve probably seen empty aisles like this one. Toilet paper, hand sanitizer and other cleaning products have been snatched up as quickly as the stores can stock them.

It’s not just anxious shoppers getting their weekly groceries who are stocking up. Last week a man who’d hoarded over 17,000 hand sanitizer bottles was shamed into donating his stash after a price-gouging probe by the New York Times.

A supermarket in Denmark has a smart way to deal with hoarding. Rotunden offers one bottle of hand sanitizer for 40 DKK ($4.09), but the price jumps to 1,000 DKK ($95) for two bottles.

“We have a great responsibility to keep the business running, and we can only do that with everyone’s help and understanding,” Rotunden staff explained.

Some supermarkets in the U.S. are limiting how much you can buy of certain items, including sanitizer, disinfectant wipes, toilet paper, and even meat and chicken. Stores are offering special hours for seniors and vulnerable shoppers, to lessen their chances of being exposed to the virus.
