You can be sure it comes out of an Amazon warehouse. And that's not the same thing.

Although frankly, it should be. I don't know how they've got this cushy position where they take items from others, store them, and then ship them out for enormous fees without taking on any retailer responsibility.

I got something recently that was "free shipping for prime customers," but when I had to return it, it turns out that it was different and returns were not free.
