I recently bought a Ritchey handlebar off of Amazon on Prime, actually sold and fulfilled by Planet Cyclery. Oddly, the bar was $10 cheaper on Amazon than through Planet Cyclery directly.

I've found that to be true for other items sold by the manufacturer. But I always check, sometimes it's the other way around.
