Stuck at home last spring and summer as cases of COVID-19 soared, Arizonans found something else to do: shop online.

Online shopping in Maricopa County jumped up by about 27% from March, when Gov. Doug Ducey issued a stay-at-home order, to May, when the lockdown was lifted, according to taxes collected for online sales. By November, it had increased by about 71%.

Those numbers don’t give a complete picture of online spending in Arizona because they only capture local purchases from retailers that don’t have stores or warehouses in the state. This includes at least the portion of Amazon sales through third-party vendors. Big-box stores, such as Target and WalMart, also submit tax collections for online sales, but it falls under a different category.

Nationally, Americans spent about 40% more online and mail-order shopping in November compared with March, according to a U.S. Census retail survey.
