What database? Assuming an sql type you do a select custid, max(date_added)
(I do most my dates as just ints of unix timestamps) group by custid having
max(date_added) > (timestamp of 90 days ago). as you select them call a
function that passes custids that come up, and the function deletes where
custid = thevaluepassed.
