I bought my CC-3065 (the same one that Shad0wguy linked to) at the Microsoft Store and they were more than happy to match Amazon's price of $25.35. The only downside was that they did not have the case in white or yellow, so I had to settle for the black on.
They had another special going on in-store, where you get $25 off your purchase of $75 or more, so I also bought a Nokia Qi charging pad (DT-900) which is normally $50. So between the case and the charging pad, I ended up spending just $50.
Side note: Microsoft is doing wonders for their brand image through their stores. There's no denying that the concept was inspired by the Apple stores, but they've done a great job of adding their own touch to it. Some of the store reps are still new and aren't always as knowledgeable about the products but they make it up with their very friendly attitude and their willingness to find answers they don't know.
