For just 95 per annum. Probably the lowest price for superior 'Expert System' software in the world! And no! Mistral won't ever hike this fee up. Mistral's annual subscription rates are now, and always have been, guaranteed for life (subject only to inflation of course). Once you become a Mistral Licensee your charges are guaranteed for life and you can cancel at any time, no questions asked, simply by no longer remitting you annual fee. You won't even have any account debited automatically. You will receive a single reminder each year but that is all.
