Several of my credit cards rebate at 2%, so I’ll use the card for anything that charges a credit card processing fee up to 2%, even more if I can avoid a stamp, envelope, and the time involved mailing it.

I just paid some property taxes with one instead of ACH; keeps all of my accounting in one place in the card, and the payment is immediate instead of waiting for the ACH payment to wind its way through the antiquated Fed plumbing. Anyone who won’t take a CC, I’ll use Plastiq; they cut a check, I pay the CC fee, but it’s still rebated back.
