I would imagine it's for a single transaction.
Actually pwiz commented here it's for the life of the sub. So if you get l+ like I am, it's 50% off each payment.
I just saw that. That's nice, but I still don't see where to enter the code.
Same actually. I would very much like to give them my money too.

Maybe it'll be corrected on June 2. lol 😆
I am certain pwiz or another member of staff will reply shortly with instructions. They are busy after all.
