Single-game tickets are first made available to the biggest-money donors, then a day later to the lesser donors, then every day they open it up to a lesser tier of CC members down to the cheapo CC members (like me) who just paid the basic $60 membership 'donation' and finally after that, to season ticket holders who aren't CC members.

I signed up for my CC membership the last day before tickets went on sale to season ticket holders, and was able to buy 4 tickets in the nosebleed section.
