I bought my get out pass in July of last year. RSL was sold out for get out pass for last year when I bought it.
In February of this year I got an email that said RSL tickets were live again on the app, me and my family rushed to get 4 tickets as soon as we saw the email as they go really fast. But we went in April.
Now I can see they are sold out. But they may or may not release more at some point and send an email.
Last season they also gave discounts on playoff tickets
