Dear Guillaume,
Could you please explain why a customer will enter any address even the address is not in your delivery area and he/she can understand you will not deliver to that address because it’s outside of your delivery area?
A customer can pickup the order even he/she is not in your delivery area. Also, a customer can order for someone else who is in your delivery area.
We are sorry to say that based on our research it’s not an issue.
Best Regards,
ThemeLooks Support Team
