Minimum purchase requirements for credit cards were explicitly legalized in the US in 2010 as part of Dodd-Frank. Merchant agreements are not legally allowed to prohibit them.
Thanks for share this. It is news to me as that used to be prohibited by the CC.
"2010 law: up to $10 minimum OK. The law says that merchants can set a credit card minimum purchase of up to $10, as long as they treat all cards the same. It also allows the Federal Reserve to review and increase the minimum payment amount."
