From July 5th until now, August 19th, there has been no response from the company.
By the way, I drove the distance and returned the package to the store. On the way home I stopped in a depressing, dark, and somewhat dirty discount store- the type of store that if you bother to "hunt" you can find a bargain. I found a stencil there for 25 cents! It wasn't exactly in the material I was looking for, but it had all 26 letters, plus lowercase letters, plus numbers, and some symbols- it'll do for now.
