Hello, dear, if you choose to pick up the goods at the grocery store, but you are prompted that there is no pick-up code at the pick-up store, you can try the following methods to pick up the goods:

1. Find a staff member at the self-pick-up shop, show the order information and identification, and ask the staff member to help you confirm your identity and pick up the goods.

2. If you fill in the mobile phone number or micro signal when placing an order, you can try to contact the customer service of the merchant and ask the customer service to help you solve the problem and pick up the goods.

3. If the above methods can't solve the problem, you can try to contact the customer service of buying more food.

Ask customer service to help you deal with the order problem and provide solutions.

Either way, I suggest you wait patiently, maintain good communication and cooperation, and ensure smooth delivery. At the same time, you need to pay attention to the accuracy and completeness of the order information to avoid unnecessary troubles and misunderstandings.
