I bought some from the place in Canada since i was in Edmonton Alberta,
www.photoblockercanada.com is located in Calgary, and they were really cool to deal with. I use it on my bike because i dont want some idoit in a car to rear end me, read this post form NY about Photoblocker and motorcycles. I can relate.

I don't need someone in a car to mess me up no one on 4 wheels pay any attention to us. the bottom of the atrical says the news crew testeddit in the plate and it worked too.
