Effective April 1, 2026, we will impose a 3% surcharge on all Credit Card Transactions, which is not greater than our cost of acceptance. Debit Cards and ACH payments will not be surcharged.  Due to this update, effective 4/1/2026, returning credit card paying customers will be required to re-enter their saved credit card number the first time making a payment.
