We're sorry, but the Shop with Points registration is currently unavailable. Please try again later
So maybe try again later or tomorrow and see if it's back up.
Just got this pop-up at checkout and successfully used it to buy a Third Party Gift card worth $50:
Use your Membership Rewards eligible American Express Card to Shop with Points at Amazon.com and get up to $25 off an order of $50 or more with promo code: AMEX16EVER
To Receive your Promotional Discount you must:
1. Add $50 or more of eligible products sold and shipped by Amazon.com to your shopping cart.
2. Enter the promo code AMEX16EVER in the box provided on the checkout page and pay for at least a portion of your order
with Membership Rewards points.
3. Up to $25 of savings will be reflected on the final order checkout page.
Following is the url for the deal:
FYI, I did try purchasing an Amazon.com gift card first but the promo code did not apply to it. So unless you already need something worth $50+ that is sold by Amazon.com, your best bet might be 3rd party gift cards such as Whole Foods, Sears, Southwest etc.
