Here are the 5% cash back promotional categories for Q4:
Discover card : Amazon.com, Department Stores and Sam's Club
Citibank Dividend : Best Buy and Department Stores
Chase Freedom : Department Stores, Drug Stores and Wholesale clubs such as Costco, BJ's and Sams Club (does not include gas or other select services)
There are some good opportunities here. I'll try and max the Amazon offer.
Discover card and Chase have a $75 maximum per quarter, which is 5% on $1500 of spending.
Citi has a maximum of $300 for the year.
