**Tax-Free Income!!**

Caveat: I don't recommend using credit cards at all unless you have the discipline to pay them off 100% within grace period. I have never in my life paid a fee or any interest to a credit card company. I don't think it's a big deal if you don't spend money that you don't have and therefore pay off the balance each and every month. This strategy has worked fine for me for full two decades.
