I am thinking about buying privelege for Shadow Slave so I can read the new chapters but I am wondering if this Privelege is permanent or if I have to buy it again at some point.
How does privelege work?
In my understanding, it needs to be bought again after the month changes into another.
So, not only after using it an month but if you start in the middle of the month it needs to be started over... 
(Its been some time though when I once tried so I don't know if there's any changes? 
)
Also, I tried this with one comic and...
Well, let's say it made me so frustrated and sad when I didn't buy another one because I needed to wait till those/we/me who don't use privilege to read ahead of others to get to that point as well so I could read it on again!
It was pure torture to me to wait half a month's worth of time (because it was about in the middle of the month when I tried and bought once) 
It makes me still shiver to remember that time 
BUT, if I'm wrong, please, people, do tell me!
