I didn't know it was going to cost money. I am just a private person trying to get Medicare reimbursement. The print is very tiny so proofreading is hard.

I had to use pdf Filler to fill out some online divorce documents, and after being initially upset at having to pay for a monthly subscription for a year to print it (very upset), I sucked it up, signed up, and have never stopped using it. Just discovered the eraser...very cool.
