In March, most shoppers on Amazon looked for toilet paper, face masks, hand sanitizers, and other essentials, as well as items for working from home, at home sports equipment, and offline entertainment. However, most of the in-demand searches returned no items in stock.

Working from home has increased demand for webcams, computer monitors, and keyboards. Consumers are buying resistance bands, dumbbells, and yoga mats, as staying at home means working out at home too. Puzzles and board games provide entertainment, together with increased demand for Microsoft Xbox, Sony PS4, and Nintendo Switch gaming consoles.

Demand for essentials like toilet paper, hand sanitizers, paper towels, n95 face masks, and thermometers hasn’t decreased since the end of February. However, those searches no longer have any results with Prime shipping or even any items in stock. Despite that, consumers continue to look for those products, showing a wide gap between supply and demand.

An indicator of the supply gap is the Amazon Coronavirus Index. Despite the demand for essentials like face masks and hand sanitizers remaining stable, the index has dropped almost in half over the past two weeks. The lack of in-stock items is the reason for the drop.

Amazon has made changes to its operations to address the rapid demand increase of essential items, while other categories like clothing and shoes shrank. The company has prioritized in-demand items when receiving them at its warehouses, as well as increased delivery items for non-essential items. Yet, it hasn’t so far been able to restore the supply of out-of-stock items itself nor has been able to utilize the marketplace for it.

“Our teams are adjusting, rapidly implementing a dizzying array [of] process and policy changes on a daily, and sometimes hourly basis,” wrote Dave Clark, Amazon’s senior vice president of worldwide operations, in a memo to employees. Some of those changes have sparked panic among the millions of sellers on its marketplace. Yet they weren’t foolproof to prevent bad actors from abusing it.
