Yeah, just updated the post. Generally shipping is free for orders $30 or more, so hopefully it'll be the same during the sale. Not that great for small or one item orders, but I can easily hit $30 on this stuff, even with the sale. I use BestSkinsEver for my iPhone since it's less expensive on a normal basis, but will definitely go with Zagg (as backups) at 50%, especially with lifetime guarantee. I also have other devices too, so $30 mark won't be too hard.

anyone take advantage of their lifetime warranty? Do you need an original receipt from them in order to get their warranty?

"Per the Lifetime Replacement Guarantee, your replacement invisibleSHIELD is free. To process your replacement request, the credit or debit card of your choice will be charged a minimal shipping & handling fee, and pre-authorized for the full retail amount of the invisibleSHIELD you are replacing. The temporary hold on these funds will "fall off" (or be released) if you return your original invisibleSHIELD within 25 days of making your replacement request. Please note that you must return your original invisibleSHIELD within 25 days or your card will be charged the full authorized amount."

My coworker has gotten his iPhone shield replaced about 3 times now, problems.
