Before contacting support
- Check that every required address, customs and payment field is complete.
- Reload the page once and avoid submitting the same payment repeatedly.
- For a swatch cart, reduce unusually large orders; fewer than 50 books is recommended.
What to send
Email support with the account email, order or cart type, the page URL, the exact error message and a screenshot. If a card payment is uncertain, do not retry until the payment status is checked.
