“Stores are not charging extra for using credit cards.”
I don’t know about actual stores, but I know that at my beauty salon and nail salon, when I check out there’s a lower price for using cash.
We use cash for most things. Of course, online purchases are via credit card.
My young dentist subtracts 10% for cash...
I usually shop at Walmart, Target, Aldi, Home Depot, fast foods, restaurants. None of them charge extra for using credit cards.
However some dentists, and most contractors charge 3% more for credit card payment. I totally believe non-chain operators such a salon etc would charge extra. My credit card pays 2 to 3% rewards for each use, so it is mostly a wash.
