Is that actually bad for consumers? Wouldn't deranking the "not lowest" price make it easier for customers to find the lowest price (whether that is a different product on the same storefront, or the same product on a different storefront), and hence be good for customers?
> 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.
It would expose distributors who are getting better deals than others when they can undercut the competition.
In the long run it is bad for consumers. If you sell widgets on amazon for $10, and amazon charges $2 or whatever, you pocket $8. Maybe you also want to sell your widgets on your own site where your overhead is only $1. The "most favored customer" clause prevents you from passing that savings on to the customer and charging $9 on your site (or any marketplace where you might prefer to sell things compared to amazon). It promotes stasis or growth of large sellers and prevents new ones from offering price competition.
