Where did you get the .020? Most of the cheap places I found online didn't carry it or were special order.
I got both the .020 and .040 thoriated at Minneapolis Oxygen. They are a chain of stores in the Twin Cities area. I'm sure you could contact them and they would take your order over the phone and ship to you. It was cheap, too!
