I use my rewards CC to pay any and all bills that do not charge a fee to do so and, yes, there are a few places that will. For me, it’s mostly my electric bill, mortgage, municipal taxes/services. I will pay as many as those type by electronic transfer but I still write maybe 2 checks per month. I alway laughed when people would come into the Town Tax Office, not want to pay the service charge and loudly announce they don’t even remember how to write a check. I tell them it’s ok, we help many elderly residents write their checks & I’d be happy to assist them too!
