You can earn 5% cashback at Amazon.com & Target with your Discover It card during Q4 of this year, from October through December 2017, on up to $1,500 in combined purchases.
You can now see and activate the offer here. It shouldn’t be a problem maximizing the spending for the fourth quarter for most people.
As a reminder, right now you earn 5% on restaurants during the third quarter. Some people also have Amazon as a bonus category this quarter.
If you don’t have the Discover It card, you can sign up and get a $100 bonus, and double cashback for the first year of card membership. All cash back is doubled, even the 5% quarter bonuses.
