We have no direct control of any third party websites. If you have an error with any third party site, we are unable to address this for you. You must contact the site directly. When purchasing a product\service from Groupon, for example, your payment goes directly to Groupon. The Coastal Dance Club only receives a very small percentage of the payment once you attend a class with your Groupon QR code, as seen below. Please bring your QR code to class as we are unable to register receipts. Without your QR code we will not be able to process your purchase and give you access to the class. FREQUENT ERROR: Should you encounter a problem booking lessons on the Groupon website, do not worry, your QR code will still work in class.
