Amex Business Platinum - 15k points for $5k spend in 3 months.

Hardly use the card beyond the benefits. Maybe if I would have read Dr. J's note about the $50/quarter angle, I would have kept it one more year at the current fee, bur I have plenty of Amex points, and the opportunity cost on Chase UR (which I go through like water through a sieve) was too high.
