I just called to cancel my Citi AAdvantage Visa as the $85 annual fee is coming up in September/Oct.
The retention rep offered me an $85 statement credit if I make 5 "eligible" purchases in the next 3 months. Any type of purchase other than balance transfer or cash advance.

I graciously accepted the offer

On a side note, I called to cancel my Amex Gold Membership Rewards Card as $175 annual fee coming up. Got a grumpy retention rep who drilled me with a few questions, made no offer, and cold transferred me to a computer which recited the cancellation disclosure.

Two very different experiences here...lol
