I keep hearing people saying “yes there are third party sellers but if you buy ‘shipped and sold by amazon’ then you’re good” These people don’t realize that commingling is a thing and that shipped and sold by amazon just means that the same random third party seller simply paid amazon a bit more and sent their items to an amazon warehouse to use their logistics. It doesn’t guarantee anything. And except amazon basics items, amazon doesn’t sell or source any of the items directly. Nor do they feel like they’re responsible for them in any way.
