Buying reduced fare or longer time passes

As well as the vending machines, 30 day passes can be bought at these locations, but there may be a service fee:

Some passes, like 30 day passes and some reduced fare passes dont' seem to be always offered in the vending machines.

Here is a report about buying from the South Strip TT
"Called the SSTT and they said you could get discounted-fare passes during normal working hours, which she defined to me as 7am to 6pm."
