iPhone Accessory Pricing Apple VS. AT&T

While cruising around looking for accessories for my new favorite gadget, I stumbled across some interesting pricing regarding a couple of iPhone accessories. 

While looking for a bluetooth headset, I notice the same headset available on both the Apple site and the AT&T Wireless site.  On the AT&T site, the same headset is $30 more expensive!

Similiarly, the dock for the iPhone on the Apple site is $29 bucks, while on the AT&T site it is $49 bucks.  Might be a slightly larger dock, but functionality looks the same.

Note to self… Never buy accessories from AT&T.  Wow.
