Waitlists move in order — first to join is first offered a spot. When someone ahead of you gives up their spot, you're promoted automatically: * **Your card is charged.** Your default card on file is charged the program price. For a one-time program that's a single charge; for a recurring program it's the first period, and Uplifter sets up automatic billing for the periods after that. * **Your athlete is enrolled.** Once the charge clears, the athlete is added to the program and you'll get a confirmation email that a spot became available. * **If the charge fails**, the spot isn't lost right away. It's reserved for 24 hours in a "payment pending" state, and a banner appears so you can add a working card and complete the charge. Miss the deadline and the spot passes to the next person. There's nothing you need to do while you wait — just make sure the card on file is current so the automatic charge can go through. **Related:** [How do I join a waitlist for a full program?](/families/families-registering/join-a-program-waitlist) · [What do I do if my waitlist payment failed?](/families/families-registering/waitlist-payment-failed) · [What are automatic (recurring) payments?](/families/families-payments-billing/what-are-automatic-recurring-payments)
