We have a shopify store in Pakistan. We are currently selling in only 1 city. The shipping is currently set up as per the zip codes functionality available with shopify’s basic account. For instance, when a customer enters a valid zip code during checkout, the system accurately charges them based on the corresponding rates associated with that zip code, as intended. However, we recognize that some customers might not be certain about which zip code to input. In such cases, they should still be able to proceed with their order even if they don’t provide a zip code. In these instances, we aim to implement a standardized default delivery charge of 150.
Is there a way to achieve this with our basic account?
A few screenshots to show what’s already set up on our shipping side.
