Brad's Deals Editor Cindy,
This iRing Premium Kickstand Set, listed at $19.99, is now $9.80 at Woot. Shipping is free when you check out with Amazon Prime; otherwise, it adds $6. This is the best price we found by at least $5. It can be used as a kickstand horizontally or vertically, or you can wear it to get a more secure grip on your phone. It also comes with a hook so that you can hang and tilt your phone in any direction. Sales tax is charged in most states.
