Where do you live, Frank?
I'm sure someone near you (to keep postage at a minimum) can send you an empty spool to get you started.
But mind you: if postage is more than the price of a cheap 120 film, the smart thing to do (even though it may seem wasteful) is to just get a roll of that, unwind the paper and film, and use the spool.
