I still have my Amex Marriott Bonvoy card (legacy from Starwood)

I thought about cancelling but last year I used all my points and achieved gold elite status

new goal is platinum status

Gold is actually one of my favorite cards as a churner.  4% restaurants and grocery.
After it renewed I told the chat agent that I wasn't getting enough value (they replied with receipts showing I maxed out all of the benefits lol) and they gave me a 20,000 points offer (after $2k spend) to stay for another year.

I cancelled my Amex card a few years ago. They raised the annual fee so told them to kick rocks.
