This is a really good deal. I've used Skinomi before on my iPhone 4S. It's not as good as SGP Ultra Crystal, but at this price they just can't be beat. It's cheaper than Best Skins Ever even when you include the postage. They usually cost $19.99 on Skinomi's site.
You can buy the Ultra Clear screen protector by itself without the full body skin for just $0.01. http://www.amazon.com/Skinomi-TechSkin-Protector-Lifetime-Wa…
Ordered two of these just for the sake of it.
$0.01 for just the front ;-) http://www.amazon.com/Skinomi-TechSkin-Protector-Lifetime-Wa…
