You are going to be really happy when you hear what Amazon doesn't sell: Live animals, including pets. Not suitable for warehouses. The massive retailer also doesn't sell gas or fireworks because, well, danger. Other things Amazon doesn't sell, mainly because of conflicting federal and state laws or licensing: Guns, nicotine products, cars, and lottery tickets.
Other forbidden items are less obvious, but probably wise: No contact lenses, not even cosmetic ones.
