Called Amex today to cancel my Platinum Card. I have 3 Authorized Users on the card. Had it for 6 years. Less than $5K of spend per year (outside of Uber, Walmart+, digital credit related spend to take advantage of the credits). My goal was to cancel unless I received a compelling offer.
After going through all the benefits of the card, the rep said there was a loyalty offer on the account for 45,000 MR points with $4K of spend in 3 months. I took the offer, and will keep the card for another year.
