I’m more inclined to think that it’s a dark pattern to shame you into keeping the money in thei…erm your account. You know, where they can use it.
Because I don’t think there would be much room to complain, after the fact, about a price you already agreed to pay, and paid. But yeah, thanks for your answer. 🙂
Edit: that was wrong, apparently US banks get more from a customer’s funds when the customer spends more, than they do when said customer has money saved up.
