Edit: Sorry folks - Disclaimer: The site doesn’t have an option to calculate shipping. I placed a fairly big order and the invoice was e-mailed today. I did order some 1/8 inch Rotary Engravable, so it was pretty heavy and shipping was up there, but I thought it was still a great price overall. Just not cheap as dirt!
I got an e-mail from BF Plastics. Their Garage Sale is on again. They primarily have 2 tone engravable plastic sheets on sale. Some are rotary only, so watch out for that, but I took advantage of the sale in the past and have made a lot of cool items. These are discontinued items, so colors are limited and it is first come first served. You may order and find that a particular item was sold out by the time they got to filling your order. Cost is $2.50 per 12x24 sheet in various thicknesses. Here’s the site address and some samples of just a few things I’ve done in the past.
Note: Remove the plastic mask before cutting and engraving!!!
