# Post-registration add-ons

Some events let you **buy add-on products after** completing registration — t-shirts, medals, donations, etc.

## When available

- **Immediately after registration** — the confirmation page may offer [premium packages](../running-events/premium-registration-packages.md) or extra questions (`apply/ok/`)
- **Later by email** — **Add products** on your [order detail](my-purchases-and-orders.md) page while the product window is open

## Checkout

1. Open My purchases → your order → **Add products**
2. Select items and variations (size, color)
3. Pay the additional amount (or confirm free add-ons)

Initial checkout add-ons are covered in [Checkout add-ons and shipping](checkout-add-ons-and-shipping.md).
