Thanks again.

All right. I now have 4197 Crysta and my account set to use the Standard 90 day plan. Hopefully I got that right. It's weird that the page where you select your plan doesn't say what any of them cost. I found an FAQ page that lists cash prices for each plan, though, so I think that should be right. In another four days I'll see whether it deducts the amount I just bought and extends my sub another three months.
