Legal Question in Consumer Law in California

California Civil Code Section 1748.1 states that "No retailer in any sales, service, or lease transaction with a consumer may impose a surcharge on a cardholder who elects to use a credit card in lieu of payment by cash, check, or similar means. A retailer may, however, offer discounts for the purpose of inducing payment by cash, check, or other means not involving the use of a credit card, provided that the discount is offered to all prospective buyers."

It doesn't sound like your daughter's school is a "retailer" within the definition of the statute.
