The commercial version of MPV is priced as a half a cup of black coffee per day ($1/day) payable on a yearly basis ($365/year). A license can be moved five times per year between different computers and operating systems but it can be active on only one computer at a time.
You are welcome to download the fully functional trial version to evaluate it and decide whether it satisfies you needs.
If you decide that it does fit your purposes, you can order it using the Bia Soft checkout. Returns are not available.
