is completely void of any logic. If I really wanted to prove you wrong, I could intentionally spend more when I use cash. Even still, I gain nothing at all by using cash for a month..I would just lose out on the free cash back I could have earned. Regardless of all of this, I really couldn't care less about proving some random fool on the internet wrong. You can use cash all you want, I dont care. I'll accept my free cash, you dont need to if that's not your thing.
