Check you local Craigslist there is a pair of soft shells for sale , for example here locally by me so there may be some for sale in your local Craigslist. You can also search the internet for breeders but shipping may be anywhere from $30 to $90 . Check local rescues & reptile shows . Maybe you will find a breeder close by.
Yeah I live in Hawaii so there are no reptile expos here I have found a couple diamondbacks for sale but I'm still searching for soft shells thanks for the advice!
