Buy Box – Make Sense

I finally own my trademark, but the Chinese accounts still show up and steal my buy box.

Here’s a thing I don’t understand regarding the buy box. They are a brand new account, and undercut my price by 1 cent and earn the buy box. Ok, they have the lower price, but their delivery estimate is anywhere from 7-11 days slower than mine.

How does Amazon consider that to be the best customer experience?
