I have this offer on my Bonvoy card, and you may too. It may be available to you if you have a Marriott Bonvoy American Express Card or a Marriott Bonvoy Brilliant American Express Card.
The offer is to get 8 additional Bonvoy points per dollar spent on purchases made using your card at Amazon, Target, and Walmart. With Target and Walmart, purchases can be at the store, online, or on the app. You can earn the 8 points per $1 on up to $3,500 in spend though December 27th.
To see if you have this offer, go to the HOME PAGE of your BONVOY card and scroll down to see your offers. It will likely be an early one on the list. You need to ENROLL in the offer to be eligible.
Eight points per $1 are pretty good, so if Bonvoy points are a currency you see yourself using in the future, I would take advantage of this.
