you'd have to call for a price quote, they could probably FAX you a current price sheet. It's about $3 - $4 a yard, depending on what you want.
All of their stuff is some form of PUL (polyurethane laminate, pul is someting a wahm came up with years ago, it's not an industry word) Their basic non-breathable is called Fabuthane. My favorite breathable of theirs (and the only PUL I like using anymore) is called Hy-fab, it's almost as thick as 2 mil nonbreathable but it's very soft and stretchy. They have another breathable one that's a variation of the Fabuthane, but I don't think it's worth it; it's very thin and delicate and it's not as breathable as the Hy-fab. I can't get their site to load right now, but they used to have a comparison chart so you could see the characteristics of the different things they have.
Denise used to be the production manager for the diapering division. I haven't spoken with her in over a year but she was a great resource. She didn't get much chance to check email, but you can fax her a note and ask her to call you back when she's available.
HTHs!!
