Last week we saw one of the better deals we’ve seen in awhile, where you could save 20% off of (almost) ALL Amazon purchases if you linked a Membership Rewards card to your Amazon account and paid at least 1 Membership Reward on a purchase. Note that you only have to pay 1 MR point ($0.01) and you shouldn’t pay any more than that because they’re redeemed on Amazon at a really bad value.
Now several blogs (DoC, and Miles to Memories among others) are reporting that there is now another way to get 20% off, potentially even if you’ve done it before. Just make sure to add promo code AMEXSWP20PD after you’ve linked your card and paid with 1 point
UPDATE: This promotion is now over – you can check here for current Amazon deals)
