This is too good of a deal not to post it, but I also wanted to throw it out there for those of you not familiar with this great product. And it's not just for GPS -- it's great for iPhones, iPods or anything with a screen that can be scratched. I just put one on my Garmin Oregon 400t touchscreen GPS and I'm very happy with the results. I've seen no noticeable degradation in visibility.
So here's the deal... Halloween Special. 40% OFF All invisibleSHIELDs
