Loyalty rewards programs?

Has anyone implemented a "loyalty rewards/frequent patron" program and tracking it in Tess?  If so, I'd be curious to hear the details of your program: is it based on accrual of "points", dollar amount reached or # of tickets purchased....and how it's being tracked in and tied to Tess.

Thanks.
