What does it cost? Well, it does it’s thing for free for the first 10 rows. So please go ahead and try it, and purchase a license from within the app (there is a purchase button in the toolbar) if you like it. You can purchase a license from within the app for 12 US $ or 10 EUR, which will allow you to convert as many vCards as you like for as long as you want.
