I mentioned this to the OP in another thread as well. Invisible Shield comes with a warranty. It's free to replace!
Do you know how much the shipping and handling is on the "free" replacement? It used to be posted on the website. 4 Bucks if I recall.
From the website:
Your out of pocket expenses may include:
* Shipping & handling for the replacement product
* Postage for mailing back your old product
* Potential customs/brokerage fees for receiving the replacement product we ship to you (international customers only)
* You will have 60 days to return your old product. If the product is not returned within 60 days, the credit card you provided during the online replacement process will be charged the full retail value of the product that was replaced.
