Pay with cash or debit card, and I pay $100 for $100.

Pay with a credit card, and I pay $98 for $100, plus if I spend the saved $2 on travel, it's actually worth more than $2. Plus other freebies for spending at least $X per year on the card.

In the US, I wish I could use one of my cash-back cards for literally everything.

And this is on a no-fee credit card! There are even better benefits available if you pay an annual fee.
