XtremeGuard cuts 80% off when you buy two or more protective screens and cases via coupon code "80off2". Even better, all orders qualify for free shipping. That's the best discount we've seen from XtremeGuard since five days ago, when we saw 70% off sitewide with no multiple item purchase required. (That deal is still available; For further comparison, we saw 75% off sitewide three weeks ago.)
