The Adsense UPS Club is basically what people say they belong to once they earn $10 000 per month in Adsense revenue. As a result, Google actually (or used to) send such checks by UPS overnight delivery.

There is also the monthly payment club. Google has a minimum payout of $100 and pays at no more often than once a month, so, if you earn more than $100/month in Adsense revenue, you're in the monthly payment club.
