Time to make your purchases to get the extra 5%
Make sure to use your Discover it card to pay for your Amazon purchases to earn 5% back now and 5% back in 13 statements if you are enrolled in the Double Double Cashback promotion for a total of 15% cashback for Amazon purchases if you haven't already maxed out on those purchases.
