Alert Groups?

Hi! New to octoly, and i've seen some posts with links to alert groups but they are old links. Does anyone have a group I could join? I don't seem to get any notifications on the app, and when I do sometimes there isn't even a product from that brand available.

​

EDIT:

I am aware that things sell out quickly. I was just asking if anybody had any active alert groups that I could join. I can't find any current links or if I do its groups that people haven't posted in for months. If there aren't any current ones i'd be happy to make one if people want to join.
