I felt misled at first feeling I needed to purchase the pdf filler after I had already used it. The customer support team replied quickly and resolved my issue.

I received some paperwork that needed to be signed and sent back to sender in a timely manner. PDFfiller was the only way I could do this. I had no access to a printer or fax machine. I'm trying to learn all of the use of the PDFfiller. I am currently trying to learn how to download some of my saved papers and sign them, then send them out. I forgot how I did it yesterday.
