Amazon, Walmart, CVS, Walgreens are limiting the number of at-home Covid kits customers can buy due to huge demand. The rapid spread of the Omicron coronavirus variant ahead of the holidays has sparked the surge -- and there has been anecdotal evidence over the past week of test shortages at stores across the country.
Amazon said it's limiting purchases of its own at-home Covid-19 test collection kits to 10 on its online marketplace. Amazon's third-party sellers on the site set their own quantity limits. "We are working hard to secure additional Covid-19 test inventory" from sellers, a spokesperson said.
