I used to live South of St Louis. I was buying GB brand wax in Dupo, IL. Sorry, but can't remember the name of the Co, but they are just across the river off 270, to the N. I don't know what other kinds of wax they carried, perhaps they also carry the C3. Was so nice at the time to drive to pick up wax. Try the chamber in Dupo, they may know the name, as the town isn't that big.
