The Discover it Cash has added Best Buy as a 5% cash back category through the end of the year. This is in addition to Amazon, Walmart.com, and Target.com.
You’ll earn 5% cash back in any of these bonus categories up to $1,500 spent from October through December. Don’t forget, if this is your first year with the card, all your cash back will be doubled at the end of the year.
And, when you buy Disney gift cards at Best Buy, you also earn Best Buy rewards, between 1-2.5% depending on your status in the program.
