This is really goofy. The reviews are hilarious. I admit I clicked on it in the first place out of curiosity, because it doesn’t seem like Amazon would be able to deliver milk without it going bad (unless it was in aseptic packs, which I do see that they have). I don’t have to worry, though… some intrepid souls even guarantee hand-delivery in the “seller” options.
If you’re bored and amused by human inventiveness, give these reviews and questions a look.
