i will second redimat. Buy in larger amounts and the saving is huge, just one mat and it isn't cost effective.
I did business with Light Impressions for years and had the same experience as Rich .
I wasn't so upset by the fact that i didn't fit into the 10,000 a year range as it was the fact we weren't informed of the change. I had a very large order that got caught in the change and was not informed of the new policy. That is not a way to keep customers. IMO
