I like Dave Ramsey ! I prefer to use my credit card for EVERY purchase and aquire “points” I pay my balance off every month to ensure I don’t pay 1 CENT in intrest. :)
You are an exception. I hear people say “airline miles” and all kinds of junk. Cash works just fine for me. I don’t need some “points” or any such stuff, and I don’t pay interest.
Dave would say dump the cards.
