While we'll need to wait to seem how the implementation works out, I like the basic idea of this basically being Fulfillment By Amazon, but without having the rely on a potential competitor. It seems like you're an importer who uses FBA(or even just lists on Amazon and self fulfills) you have a short window to make money before Amazon eventually moves in on you to start selling the same thing. Even if you're selling your own stuff, you might not be safe(there's some kind of laptop accessory that I'm trying to remember that basically had an Amazon Basics version come out after being on Amazon for a little while).

Don't take this as being against big evil Amazon(I buy tons of stuff from them), but I'd rather them not be the Walmart of the internet that puts all the small web shops out of business.
