You may be able to get single-ply all-cotton terrycloth pads from Argo at that price, if they are on the small side - say, just large enough to fit on a Challenger pad driver, rather than the large 19" pads supplied by Challenger. Go to
www.argoco.com. You can't order anything directly from the website, but get the phone number there and call them. They custom make pads to any size, in both single and double thickness. That's where I order the little pads intended for use with the 6" orbital stair machines included in my Package.
