Ludovica Tomaciello had never shopped on Amazon before being trapped at her parents’ house in March during Italy’s coronavirus lockdown. Bored one afternoon scrolling TikTok, she spotted hair scrunchies that she then tracked down and ordered on Amazon.

When the package arrived, she was hooked. She soon signed up for Amazon Prime and turned to the site to buy a tapestry and neon lights to decorate her bedroom; halter tops, jeans and magenta Air Jordan sneakers; and a remote to wirelessly take selfies for Instagram.
