And on this note, I was talking with my neighbor yesterday and he's having a related issue that only became an issue when Amazon enacted this covid-response policy. It used to be that it didn't particularly matter if your products were accurately mapped into Amazon's categories as long as they were searchable. Now, however, Amazon is refusing to ship (or receive FBA stock) for non-essential categories. My neighbor is a shoe salesman for a brand that has a full medical & industrial line ... but they weren't tagged into medical equipment categories at Amazon so he can't ship replenishment inventory. Amazon isn't allowing these mapping adjustments to be made at all right now for fear of abuse.

Also, when FBA stock depletes, sellers have the individual option of whether to direct ship or not. Some are, and some are using expedited shipping, but others are either not shipping at all or are using the cheapest freight possible.
