How about a free (after rebate) nice I-Rocks USB AC adapter with foldaway prongs, and with free shipping besides? And if you have ShopRunner, you can get free 2-day shipping.
5V 500 mA, good for portable music players and the like, including the Clip. I have the same or a similar design and find it handy for travel and portability, with the foldaway prongs.
Good through 6-30-13
