Some changes are self-serve, some need support.
Self-serve
- Shipping address — change before the order is shipped from Account → Orders.
- Delivery slot — pick a new slot before fulfilment cuts off, where the courier supports it.
Needs support
- Swap a variant (size / colour) — write in within 30 minutes of placing the order. After that we recommend a return-and-reorder.
- Add or remove items — same; first 30 minutes only.
- Split shipments — usually automatic when items ship from different warehouses.
Contact support with your order number and what you'd like to change. We'll reply with whether it's possible and what (if anything) the price difference is.
