A. It could be very frustrating to try to keep track of all the different rewards cards' reward categories and percentages. Below is a very simple way to achieve absolutely the best results:
1. American Express Blue Cash Preferred
Use this card to get 6% cash back on groceries and 3% on gas.
2. Fidelity Rewards American Express
Put everything else on this card to get 2% back.
The only problem is both cards are American Express cards which are not accepted everywhere. In that case, keep a Barclaycard Arrival World MasterCard, you can earn 2 travel miles for every dollar spent.
