Now I'm wondering if I should wait for a 3 for 2 too. If had four credits, would they let me buy 6 for 4?
This offer is effectively a 5 for 4.
I also think I'm going to cancel my membership for a while after the next bulk purchase. I'll have enough listening material either way to keep me occupied for a long while.
Edit: Instead of canceling, I may move to the light plan mentioned above and here:
