@Kenmac & Lunaseas -- that code, according to the comments on the video, is only good for a one-time top up of 100 credits. When asked about it the author of the vid -- who by the way uses an artificial voice and is apparently more focused on "getting rich with AI" -- did clarify that she (?) mistakenly said that and it is just a once only bonus when you sign up using her code. If you want more free credits, you have to bring in more members to the site. 

There were also complaints about excessive slowness and not as much value in the free package as claimed because to get best use you need a paid plan that'd cost more than MidJourney but still not give as good results as MidJourney. That said, there was much praise from other people who tried it, so it's probably worth checking out. Just be aware that code is not for 100 extra points every day but only on the first day you sign up with it.
