Fred, There is a Branch of Physician Sales and Service Co.(PSS) in Clackamas 253 929-1700 that can get you 4oz of 1% Silver Nitrate for about 25-30$. They get it from a manufacturer in Jacksonville Florida named Healthlink. The PSS part number is 104830. It would be easier for your doctor to order it for you because it may be a little bit of a hassel for a customer service person to do an order for someone who does not have an account set up, but they might do it. It depends on who you get to talk to. Lots of doctors order from this company. Dan
