Great price on sorbothane sheets

If you've ever looked for sorbothane in flat sheets, you've probably seen the 6"x6" sorbothane tiles sold by various dealers for $20.

How about a 12"x12" sheet for a dollar less ($18.95)?. Edmund Scientific has it in their online catalog. Here's the link: http://scientificsonline.com/product.asp?pn=3037000
