Yep, though you can technically pay for advance months/years by buying enough Crysta but as of now that's the more expensive route as, given a $12.95 month fee, it's $30 for 2 monthsish, $50 for 3 monthsish and 100+ for 10,000 Crysta which would be a few months give or take depending on finalized pricing.

However they are changing things around which should be put into play by next month. (late fall)
