Amazon is saying that sellers cannot offer a fair low price to customers on other platforms if the seller can't also offer it on Amazon. This is 1) anticompetitive, 2) anticonsumer, and 3) insane.
Consider this test:
- Seller buys a crappy LED bulb from China for $0.80
- Seller is happy to list the bulb on Walmart, Target, etc, for $2.00. Net of fees and shipping and stuff they make enough money
- Amazon charges $3 in fees. Obviously the seller can't afford to sell for $2 on Amazon. They sell for $5 instead.
- However, now the seller also can't sell for $2 on competing sites. Amazon, leveraging its market share, has dictated that the seller must price Amazon's fees into pricing on non-Amazon sites, so consumers pay $5 to Target for something the seller would have been happy getting $2 for.
This is insane.
