This is one of the few annoyances of shopping at Amazon. As a Prime user, I usually don't want to deal with anyone other than Amazon directly.

There's a search filter option to select "Prime eligible" items, but when you select it, the price sorting still seems to include Marketplace vendors. Selecting the "New" search filter does not help.

There's even a search filter for "Seller" that allows you to select only amazon.com, but the price sort is still wrong if this is selected!

(I understand that Amazon probably prefers that we stumble upon the marketplace vendors, but it's frustrating when you can't disable it even temporarily.)
