First things first, if this been asked before, I couldn't find the answer, because I'm dumb and didn't know where to look for, if that's the case feel free to remove this thread and everything.
So to the actual question, fictional situation here: I buy the low tier passport, allowing me to get just the beta acess, if I want to upgrade let's say to Biker (wich is the one I wanted) will I be paying $ 130, or the Biker one becomes $ 70?
Unfortunately, I don't live in the US and in my third world country I pay more than triple the actual price, I just started working so using my first pay to get something for 300+ is an investiment that I really need to carefully think about.
