The monthly plan provides the convenience of washing as defined below for a monthly price. The plan requires authorization for AW Auto Spa to charge the cost of the plan to the credit card you provide on the same day each month. The program can be canceled by either party. Participation requires a remote frequency identification (RFID) tag to be installed on the vehicle. The tag may not be moved, removed, damaged or used with a different car. The monthly fee may be increased without notice, but should be posted at AW Auto Spa 30 days before it changes.
