I didnt grab a quote, but for the sheet I bought, it was $13. It's 4.5 X 2.5 at 1/8 inch thickness. The guy at Redwood Plastics just guess-timated a price on the spot. He takes Debit, Cash, and I assume Credit as well.
I hope Lexan is cheaper, I thought it was more considering it's more reliable, can be sawed, and in thicker densities can actually be used as a real knife resistant material (in the case of stabbings).
