Paradigma Software announced on the blog that there is now volume pricing available for Valentina Studio.
In addition with Valentina 5.8.5 (released today) and later, there is now the Valentina Studio Pro Universal license available; one license lets you work on Windows, Linux and Mac OS X. This is ideal if you are a single developer but you need to work on three different computers (with three different operating systems).
You can also use the RENEW of Valentina Studio Pro Universal to UPGRADE from a single OS version of Valentina Studio Pro.
