Platinum Personal - $4k in 3 months, $300 credit.
Amex customer since '00. Platinum holder since the 100k point bonanza of whenever that was.
Called to cancel a few nights ago with AF coming up at the end of the month. Recommended I speak to Retention first (which was closed at the time). Retention offered the above deal or downgrading to Gold. Took the offer. Low spending (less than $5k) the past two years on this account as everything's moved to CSR card.
