Heads up, deal hunters! Some Amex and Discover cardholders are being targeted for a sweet Amazon Prime Day promotion. You could snag up to 40% off your purchase simply by using your points. Now, usually, we preach against using credit card points on Amazon because you rarely get good value. But a discount this big is a total game-changer! This is definitely worth checking out because it could save you serious cash on those Prime Day goodies. To see if you're eligible, head over to Amazon and look for the offer linked to your Amex or Discover card. Even redeeming just ONE point to activate the discount will unlock the savings, leaving the rest of your points untouched for better redemption opportunities like travel. Don't miss out on this easy way to maximize your rewards during Prime Day!
