Very similar to the Amazon/American Express $20 promo (since expired), Amazon is now running also a somewhat targeted promotion with Citibank. Amazon is offering $10 off your order when you pay any portion of your order with Citi Thank You reward points. The great thing is that just the like the Amex promo, you can use as little as just 1 point to trigger the $10 off!

Purchase must be placed by Nov. 23 2014.

To get this deal:

1. Link your Citi Thank You rewards account to your Amazon account via this link.
2. Add any item/s that are sold and shipped by Amazon.com totaling $10 or more to your cart. – Note this does not work on Amazon gift cards, though it does work for other merchant gift cards such as Staples, Starbucks, Nordstrom and loads of others!
3. At checkout, select the Citi Thank You reward point credit card that that you linked with your Amazon account and choose pay with points.
4. Choose the amount of points you wish to pay with.
5. On the next page, enter promo code SWP10TYP and hit apply.                            
   
6. $10 discount will be reflected on the final order checkout page!

Note: This offer only works on Citibank cards which are part of the Thank You Rewards program. This does not work on other Citibank credit cards.
