Amazon has a targeted promotion offering a 20% off your Amazon purchase (max discount $50). This may be targeted to people with an eligible American Express card with Membership Rewards points linked in their Amazon.com account. If you have one that isn’t linked, you may want to try adding it and then checking the link again.
After activating the offer, add only items shipped and sold by Amazon to your cart. During checkout, you only need to spend 1 single American Express Membership Rewards point after choosing your linked AmEx. Verify that you see the 20% discount before finalizing your order. Your maximum discount is $50, which means you could get $50 off $250 in purchases. Not applicable towards Amazon Gift Cards or third-party gift cards.
You could use this on things that are rarely discounted, like getting $50 off Bose QC 35 headphones. I’ve been eyeing the biggest 8-quart Instant Pot after reading this NY Times article about thinking of it as a slow cooker replacement. (The 8-quart goes on sale a lot less often for some reason.)
The wording suggests that you can come back and make multiple purchases at Amazon, and as long as you use 1 single Membership Rewards points on each purchase, you’ll keep getting 20% off until you reach the maximum discount of $50.
