Fpr developer purchases, you pay $99/yr for the first interval and $33 (or close to that?) for the second interval.
I have heard that for resale intervals, they are charged $99/yr, even if the owner owns a developer interval, but I have no experience with those. Maybe some resale owners can clarify. Not sure what happens if you own, say, 3 resale intervals. I wonder if you pay $99 x or do they have you pay the subsequent interval rates!?
It would be good to hear from someone who owns a developer and resale, and someone who owns 2 or more resales.
