Where can I get NO-DAMP?

Question:I've been looking around at Home Depot and Wal-Mart, and I cannot find it. The only place on the internet that I have found it is on ebay, but that has to be shipped from Canada.

If anyone has a website of someone that sells it or if you know what stores DO sell it it would be much appreciated.

I live in Austin, Tx. if that helps.

I use to buy No Damp at Kmarts. It is hard to locate in the store but I have seen it there. You also might try a hardware store. They sometimes have odd things
