Where do they sell plastic that i can build with?

Tinkz: Where do they sell plastic that i can build with?
I sell stuff at the swapmeet and i want to make a plastic table top cover type thing so i can stick stuff under it that people can still see but not touch. Does Home Depot sell plastic like that? A thick plastic?

Sure, I have seen it at Lowes and Home Depot.
There are two types; Plexi Glass and Acrylic.

Plexi is cheaper but it breaks easier.
The Acrylic is a bit more money but remains much more clear and is stronger.

You can get it in many different sizes and thicknesses.
Boat stores and marine centers usually sell it too.
