At ZAGG, when you buy one invisibleSHIELD, you get a second one for free. (You must add two to your cart to see the discount; free shield must be of equal or lesser value.) That's the first such offer we've seen from ZAGG. (We've seen 50% off invisibleSHIELDs at Zagg on several occasions.) Shipping starts at $2.99, but orders over $29.98 receive free shipping. invisibleSHIELDS are available for the iPad, iPhone, Amazon Kindle, and other devices.
