Humble Bundle is a website that offers software and media packages at various price points, starting at $1. Part of their revenue from selling these packages goes toward charity. One of their packages currently offered is selling Pinnacle Studio 24 for only $1. As I have purchased from this website before, I can attest that this is not a scam.
Unfortunately, as I have never used Pinnacle Studio I cannot attest to its quality, but it may very well be sufficient for the needs of many of the casual users who visit this website. Note that this is $1 for a perpetual license, not for a subscription.
