faa has stuff on amazon. couldn't tell you if it works or not, its more expensive, and its impossible to find stuff unless you have a very good title. you can't just put stuff up on amazon, doesn't work like that. as it is the site is very picky about what does go up there. unless we are talking about two different things because i'm not sure what an amazon store is exactly. i wouldn't chance it because you would have to deal with a customer if there is a return, and then there will be a lot of back and forth since you don't have a direct inventory.
