I found out recently that there are actually a few levels of "Amazon Prime" sales! The "Shipped and sold by Amazon" is what we normally expect, but there's also "Fulfilled by Amazon" and a third tier that's effectively "Prime Shipping" but is treated as a third-party seller. That third tier is particularly deceptive because the sidebar display doesn't distinguish between the second and third case but the return policies are very different.
