HP touchpad keyboard 55 for 2 (+ 5 dollar fillers and shipping)

I just got two keyboards for 55 dollars, needed 5 dollars in fillers and paid 10 dollars shipping. I also had to pay 3 dollars in tax and it goes without saying that tax is YMMV.

The actual deal is buy three accessories and get 15% off (four for 20%). I didn't know of any free shipping codes, but if anyone knows how to get that from Best Buy, it takes it from a good deal to a pretty great deal. You can get the keyboard for under 30 a pop, which is below what I am seeing for anything else.

If anyone knows of a good case for this, I'd love a link so I can get one for my touchpad, but now that I have it I can just test it out with different models. Also is there a good thread discussing the touchstone?
