Amex cards too.https://www.dansdeals.com/credit-cards/earn-6-points-per-dollar-groceries-select-marriott-cards/
For the numbers people. Is this 6x more valuable than the 4x on the Amex personal gold ?
My Amex spg card which was converted to a Marriott bonvoy will get 6 points per dollar? Is there anywhere on the website that says that?
