I love ordering from Amazon! Here is a nice promotion where when you use at least one Citi ThankYou point to pay, you can score 30% off select categories. You can check out this promotion here.
Amazon 30% Off Select Categories With 1 Citi Point
Each person will have different categories and coordinating promotion codes for each category.
See here how you set up you Citi card to pay with points. You will need to have a card on file to do so.
30% off is awesome! Happy Shopping!
