want to buy Printshop 3

With all the many, many reported issues with Printshop on this forum, I think I would stay as far away from Printshop as possible. There are excellent alternatives out there. One is Swift Publisher. It is a more robust desktop publisher, but at least it is supported.

Check the Mac App Store and if it is not available there, contact the developer.

The Software MacKiev vendor though headquartered in Boston, has its principal workshop in Kyiv, Ukraine. That could be an issue going forward due to the current military circumstances in Spring 2022.
