Yep, you have to filter for free shipping. You also have to filter for fast shipping, or you might get some "Two day shipping (ships in two weeks)" bullshit. And then you have to mentally filter out the "sponsored" results which may not be what you're looking for at all. Searching for a hard to find hat size? Top result is perfect, has free same day shipping, and is a reasonable price. Oops, except when you click on it, you have to pick a different size, which isn't available in that color, costs more, snd ships out of Mongolia.
Fuck Amazon Prime.
Although Fallout was good.
