The 148th most popular book on Amazon Wednesday wasn’t actually a book at all: It was a package of 50 disposable face masks—the kind that shoppers have scrambled to buy amid the coronavirus pandemic. Surging demand for masks, as well as supplies like hand sanitizer and disinfectant wipes, has emptied store shelves, and in some cases led to skyrocketing prices on Amazon.

The box of masks had risen in sales rank from 19,662 to 148 in just one day, according to Amazon’s list of “Movers & Shakers,” or goods that have surged in popularity in a given category in the past 24 hours. A similar scenario played out the next day: The number two Mover & Shaker in the videogames category Thursday morning, beating out The Sims 4 and a gaming headset, was a package of 50 disposable face masks. Both of these product listings for masks appear to violate Amazon’s rules.
