Well, membership has its privileges!
According to Lifehacker, you can use your American Express rewards points for purchases on Amazon!
In some cases, doing so can get you as much as a 20% discount off your purchase.
You should note that not all Amex cards are eligible, but some like the Senior Green Card, or the traditional Green card will work.
All you have to do is to link your AMEX card to your Amazon account, and you’re all set.
While your points worth may fluctuate, you can split your payment between points and credit and still get the 20% discount.
So, what are you waiting for? ... Time to shop!
