Hmm, I'm not sure how you could tell if anyone has one for sale. According to the database insert for Gymnocalycium mihanovichii, there are three people (including myself) who own a Gymnocalycium mihanovichii (but if the other two have var. friedrichii, I don't know). My Mother found mine at a local Lowes this Spring; it was a gift. It was grown by Cactus Collection (they do have a website if you want to check it out). This is the first one I've ever seen in town, unfortunately. I wish I could steer you in the direction of places online you could find one to purchase (if you wanted to do that), but I rarely buy plants online. Sorry.
