Amazon is offering 20% off purchases sold by Amazon, in addition to various gift cards not sold by Amazon, for those that apply at least 1 Membership Rewards point to their order and pay with the Amex card that earned it. The maximum discount is $50 on a $250 order. Note that while widely available, it does appear that this is a targeted offer.

If the promo lasts (see point B in the first bullet of the terms and conditions in the conclusion), then you may be able to stack this offer with Amazon Prime Day which this year will span over two days: July 15 and 16.

Here’s what to do.

If it’s not already, add your Membership Rewards-earning Amex card as a payment method to your Amazon account.

Navigate here. If you see the following screen, congrats, you were targeted.

Click the “Click to activate” button to apply the offer to your Amazon account.

Now you can shop. The 20% discount will only apply to products actually sold and shipped by Amazon, as well as select third party gift cards. You can check if a product is sold by Amazon in the product description where it should say “Ships from and sold by Amazon”, as circled in the screenshot below.

If there’s nothing you need from Amazon today but you want to cash in on this awesome deal, buy a gift card you know you will use in the future from a third party retailer instead like Airbnb, Southwest, Uber, and Whole Foods… some place you know you will spend at anyways. They are also 20% off if applying at least 1 point. I know it expressly says in the terms that third party retailer purchases don’t count, but the proof is in the pudding. My Airbnb pudding shows as 20% off ($199.99 instead of $250):

Once you find what you want, check out and change your payment method. Choose to pay with a card that earns Membership Rewards, and then scroll down to the Rewards Points section. You’ll be able to apply Membership Rewards from the account that you selected to pay with. Amazon will try to automatically apply all the Membership Rewards you have earned with that card to the purchase (DON’T FALL FOR IT), but you can manually change to as low as 1 cent (1 point) applied and the discount will still trigger.

The discount can be applied to multiple purchases before maxing out.

Bottom Line
