Thanks for pointing out that the videos are downloadable rather than physical disks. I guess the price covers production costs but I'd rather put that money towards a good book!
It's surprising in a way that they haven't loaded the production costs into the advertising budget and made the videos free downloads. Nothing like a spot of goodwill to encourage sales.
Anyway, I'm glad I shared the fact that the videos are available even though I was, when I found the reference to them, looking for breaking news from Canon.
