> Wouldn't deranking the "not lowest" price make it easier for customers to find the lowest price

The original wording was

>Amazon requires that anyone selling through their platform not offer lower prices elsewhere online.

which means if the seller offers to sell something on amazon for $x, but has a shopify site selling it for < $x, then that seller will get deranked. That's not the same thing as the lowest price, because it's possible that other sellers sell for higher prices, and some people might not find whatever obscure shopify site that has the lowest price.

The wording is admittedly ambiguous, but the fact that there are totally overpriced items available on amazon suggests amazon isn't deranking people just because it's not the best price on the internet.
