A shared shuttle is free to cancel from your trip page until 2 hours before pickup, whether you started it or joined it, and the hold on your card is released in full. Everyone else’s price goes back up, but never above what they were first held at. After that it’s non refundable, because the final price is set then. If you miss your shuttle, you can hop on a later one that day with free seats at no extra cost. A private shuttle is free to cancel up to 24 hours before pickup. If nobody joins, the shuttle can’t run, or we or the firm cancel, you get every penny back.
