I agree with this article. I was at the DMV today renewing my drivers license. I owed them $26. If I paid by card it would cost $28. I literally found an old check I never used and wrote the DMV a $26 check to save $2 on processing fees. I’m one cheap bastard. I actually thought about my “frugal” ways a little after that, and felt reassurance to know that many of my entrepreneur mentors are the same way.
