Forgive me if I missed the a comment that actually got why amazon is doing this and therefore why it should be illegal. This is not about getting the best price for consumers on amazon. This is about stifling competition for selling products at competitors to amazon because amazon has hugely marked up fees to sell there vs pretty much everywhere else. By ensuring your item has to be priced the same on competitors sites it negates the ability of amazon's competitors to compete on price, which protects amazon's entrenched position as the market leader in online marketplaces. This needs to be illegal because online retailers have differential costs and should be competing on price (among other things) to sell products because when they do the consumer benefits and businesses get more efficient so society benefits as a whole as well.
