>>You will find the Dr. Scholl's device (which looks similar to an oval-shaped crock pot) at most Wal-Marts or other pharmacies. Runs $30 to $40 and comes with an initial supply of wax to which I add an extra cake or so to make sure it goes well onto my wrists as well. Replacement wax runs $6-7 and if you keep it covered when not in use, you should only need to replace the wax bath once or twice a year.
