(2) impose any requirement, condition, penalty, or fine in a contract with a merchant to prevent the ability of any merchant to set a minimum dollar value of no more than $10.00 for its acceptance of a form of payment, provided that if a minimum dollar value is set by a merchant, it shall be prominently displayed and printed in not less than 16-point boldface type at the point of sale;
