Both the Super Mario and Zelda analog thumb stick grips are selling on the website and in store for $12.95. Still priced up at $19.95 and the staff were as surprised as me (image of receipt here).
Not bad if you want to protect your beloved controller. Made by ThinkGeek if you're curious.
Mario one looks better to me than the Zelda one. Zelda should be blue and white imo but the "Aussie" green and gold is okay.
I took a pic of both so you can see for yourself: http://imgur.com/a/PEWCbPW
Highly recommend Skull & Co grips if you are into these sorts of peripherals.
