If you put everything on a good cash-back card, and you pay off your balance every month, it can really add up. Let's say you run $30k a year through your card and have something like the 2% cash back Citi DoubleCash Mastercard. That's $600 a year you're foregoing by not caring about cash back. Just a thought.
It's not that I don't care about cash back, but I would simply prefer prices in general be 2% cheaper rather than having to claim them via a cash back card.
This type of thing warps price perception and just passes the costs back onto consumers in other ways.
