Beats my deal from a month ago. Guess it pays to be patient!

This is a PDF editor (Windows only) that can be used to edit, annotate, sign, create fillable forms, import/export, etc.
Version with OCR also available for $10 more.

If you just need basic split/merge/rotate functions a free version is available - https://pdfsam.org/pdfsam-basic/
