<prompt> Human: I currently use BOA cashback rewards and I feel like I could find a better rewards card.My monthly spending is pretty much food and gas... I dont really buy much groceries, probably should ... but even then during the week I will always eat out twice a day when at work.Anyways, my spending primarily consists of eating outrestaurants, gas, and amazon. Im pretty sure about what cards I will go with and how to use them, but Id like some input from this sub. Im thinking the Amazon Rewards card with 5 percent cash back is a must for me... but what should my everyday card be? Citi Double-cash? And even with that card, I would still want to use my BOA card for gas, right?  <response>: I use Citi double cash for everything, and then the Chase Amazon card which gives 5 for Amazon purchases if you have prime.In my opinion, if you have mental energy to spare on CC rewards, you should be focusing on your eating habits first. Optimizing rewards points is worth about 1day. Packing meals is worth 10day.
