> sued Amazon for prohibiting vendors that sold on its website from offering discounts outside of Amazon... to make sure that sellers can’t sell through a different store or even through their own site with a lower price...

First, this is not new. It's been stated policy for years.

Second, manufacturers get around it in a clever way. They always list their items on their own site at the same price as at Amazon... but then magically almost always seem to have a 20% or 25%-off sitewide coupon available, whether it's for first-time customers, or "spinning the wheel" that pops up, etc.

So I don't know how much this is really raising actual prices in the end.

Otherwise, I'm not sure how to feel about it, because pricing contracts are common on both ends. Manufacturers frequently only sell to retailers who promise they won't charge less than the MSRP, and large retailers similarly often require "most-favored-nation" pricing, so they can always claim they have the lowest prices. If you want to end these practices, then it's only fair to have a law prohibiting it across the board, rather than singling out Amazon.

They raise prices by 30 percent to offset Amazon's taxes and then offer a 25 percent discount on their own site. How does this not raise prizes?

It prevents other sellers from competing with Amazon.

This is irrelevant.
