Note that American Express no longer issues free Gold cards on personal Platinum accouts. The free cards are now called "Companion" cards, and I believe they are white. I do not know if a Saks purchase made with a Companion card would be reimbursed. I think it should be, but I have not researched.
thank you for the reminder. thats a great point. i actually dont know either after free gold AU became white. assume the white companion card still has same benefits. but ur rite. we should make note.
