Online Source of Hydro-Stone
- I found a seller on eBay that sells 20# lots of Hydo-Stone and uses USPS Flat Rate boxes to ship. The cost is $10.95 plus $9.85 shipping for a total of $20.80 per box delivered to your door. I talked to fellow on the phone & he says he usually keeps Hydro-Stone in stock and that the Post Office winces everytime he comes in to mail something.
