I spent approx $70 for PDF Filler, could not find a page rotate icon when I really needed it, then a screen popped up that I would have to spend $120 per year to have this additional function. I was in the midst of needing to reorient some legal documents so paid the additional money. I find this to be less than fair business practice as when I signed up there was no clear breakdown presented on the functions available for different costs.
