That’s what I use. I have it deposit in my daughters 529 college fund. It’s not going to pay for her school alone but it’s going to be a decent amount of money by the time she reaches that age (I contribute to it separately as well but specifically the rewards dollars will add up to something in the five figures with growth and all that).Fidelity Rewards Visa. 2% back on everything, cash deposited into a Fidelity account. No fees, no limits, no screwing with miles, redemptions, or any of that crap.
