I thought about those other cards. I actually have an invitation sitting on my desk from Discover It. But considering how much we spend on groceries and gas I opted for the 6% on groceries. We live in a high cost-of-living area. For a family of three, we spend a little over $450/month on groceries. As my child gets bigger, I'm sure that will increase.
We have one car, but drive it enough to spend a good amount on gas. So, the 3% helps there.
I just don't have the time or patience to track rotating cash-back categories. I'm a set it and forget it person. I just want to swipe like crazy and know that I'm getting cash back without having to check in every quarter.
Congrats to ya !!!
