Right now at Amazon, some American Express Membership Rewards Cardholders are eligible to receive $30 off a $60 purchase. Now, this deal is targeted, and that means only some customers can redeem it. Your mileage may vary. Follow the instructions below to see if you can get in on this awesome discount. If you can't, please don't roast me, because I can't either.

First, click here to link your American Express Membership Rewards account to your Amazon account. Then, click here to activate the promotion. If you aren't eligible, you'll see a screen that tells you so.

Are you one of the lucky ducks that essentially just got a free 50% off coupon? Then it's time to shop. Add at least $60 of goods shipped and sold by Amazon.com to your shopping cart. To save even more, peruse Thrifter for eligible discounts and deals. When you're ready, proceed to checkout and use your AmEx card as your payment method. Use at least one Membership Rewards point towards your purchase. The $30 discount will come off automatically during checkout.

Note that this limited time offer can be finicky. If you haven't linked your AmEx card to your Amazon card, you might have to wait a day or two for the promotion eligibility to show up. The offer isn't valid to eligible cardholders that have redeemed a similar offer in the last year. You can check out more fine print on the offer page if you are indeed eligible.

Did you miss out on this offer? These are the cards that are generally eligible for similar ones. Obviously, do your research before applying for a credit card, but that resource is there should you need it.
