Not for free to send it and save to computer. Almost $7 for a year isn't bad though! But I'm not sure if i'll be using this all the time though throughout the year.

My experience was good with pdfFiller. I just don't feel that I would use it enough to keep the extra expense! This was my response and I truly liked it a lot but I don't think that I would be using it enough to warrant the extra expense.

I only just started using it I only just started using it, so only 4 stars, but I don't see any issues other than the lack of fonts in the signature section. Seems to be a solid app.
