SuperCart: Form as a Shopping Cart
SuperCart allows a customer to submit a form multiple times to register multiple attendees to an event then pay once for all of them at the end. SuperCart can also be used to sell any goods or services where each item sold has several configuration or pricing options and you want the buyer to be able purchase multiple items.
For this demo, we've created an order form to sell premium hand-crafted Christmas cards. A buyer can purchase several cards, each with a different design, message and options.
