Debit Card Minimums Illegal?

I want to hear from certified financial planners, bankers and other financial experts. Can you be required to purchase a minimum amount before you can use your debit card? What’s legal, what’s illegal, if anything? If you are denied the ability to use your card, what recourse, if any do you have? I want to hear the facts about what you can and can’t do, and more. Send me
your thoughts.
