Tide laundry detergent is a big one. People steal it by the cartload, and either relist it themselves or sell to unscrupulous resellers who list it themselves.

Pretty much any fungible commodity that grocery stores sell that's easily stolen, if it's available on Amazon almost certainly has stolen instances mixed into the supply chain, especially with FBA items.

Guarantee there's plenty of people making decent money doing this in San Francisco and other cities that no longer prosecute shoplifters, there's literally no risk or downside.
