Amazon is offering $15 off $50 when you use a Membership Rewards eligible American Express card with their Shop with Points feature. To get the discount you must purchase $50 or more of products sold by Amazon and use the code SWP9AXP15 when checking out.
It seems that this code should work on all Membership Rewards eligible cards that haven’t been used on Amazon in the past 24 months, so you may be able to get the discount more than once. The code does also seem to work on third party merchant gift cards sold by Amazon. Also note that this is technically a targeted promotion, so it may not work on all accounts.
- This is a limited time offer. The promotion will end at 11:59 PT on 11/13/2015, or while supplies last. The promotion code will expire concurrently.
- You must have an Amazon.com account to redeem the promotion code. If you are creating a new Amazon.com account, please be aware that it may take up to 72 hours before your promotion code will be accepted and applied. Accordingly, you must create a new account on or before 11/10/2015 in order to redeem the promotion code.
- Offer applies only to the purchase of at least $50 of eligible products, where Membership Rewards points are used for at least a portion of the purchase and the promotion code is entered at checkout. Taxes, gift-wrap, and shipping and handling charges do not apply when determining minimum purchase amount.
- The maximum benefit you may receive from this offer is $15 per eligible Membership Rewards enrolled Card.
- Enter the promotion code at checkout through the Amazon.com shopping cart. After redeeming the code, a credit of $15 will be automatically applied to your eligible purchase as long as Membership Rewards points are selected as your method of payment, at least one Membership Rewards point is used for the purchase and your shopping cart contains at least $50 of eligible products.
- Offer is not available to American Express Membership Rewards eligible cards whose points have been previously used for purchases at Amazon.com in the past twenty four months.
