I just built a site that notifies you when movies or TV shows you care about are added to the Netflix streaming catalog. It's in beta right now and I would love some feedback on it.
The idea is fairly simple, create your wishlist of TV shows and movies and it'll send you a notification whenever any of them becomes available on Netflix streaming. It's called StreamThing and you can find it here https://streamthing.co
$5/mo to track a $8/mo service? Isn't that a teeny weensy little bit completely disproportionate? Especially since it's possible to sign up for 1 DVD for only $3/mo more than what you want to charge. And for that $3/mo extra I get a DVD shipped to me and I get a saved section that shows when movies or TV shows become available for streaming, without having to bother with a third party site like yours and without needing email notifications.
Knaldskalle, there is actually an option for a free Basic account which allows you to track 5 movies at a time and the 'Pro' version is only $1.99/month which is still a bit cheaper than signing up for the Netflix DVD :-)
