I’m not sure what you’re asking to purchase because you don’t state it, if it’s the patches that are being talked about I don’t know. If you’re talking about the Theracane, I bought it at a medical supply store that’s in my doctors office building. I have also seen them online, I believe at Amazon. If you Google them you’ll find them. If you want it right away go to a medical supply store. I’d call first to make sure they have it.
