The new MacUpdate, bundle is available for $49.99 and includes includes TechTool Pro, ScreenFlow 4, PDFpen 6 and SnapHeal Pro and other apps. As a special bonus, for $20 more you can upgrade to PDFpenPro if you need the extra capabilities including the ability to create forms, bookmark PDF files and download Web sites to PDF. I already own and use all of these apps, otherwise I'd be all over it.
Note: A prior version of this post stated, PDFpenPro was available for $20. That was an error and has been corrected.
