CuriosityStream, which I've mentioned before here (https://plugintolinux.ca/forum/index.php/topic,891.0.html), is offering a deal where you can get an annual subscription for $12 USD (https://curiositystream.com/referral/99060adacb) which is 40% of their regular rate of $20/year which is already a crazy deal. We're been subscribers for a number of months now and quite enjoy it. It's like your own on-demand science channel.
