We came across an issue while using Zapiet's - "Store Pick up + Delivery" app, and need some help and advice.
Using Zapiet's app, we loaded a list of post/zip codes available for delivery:
A Customer placed an order for their post/zip code, that is not in the list above, and got the same delivery option as per the post/zip codes above. We thought it may have been a glitch, so we tested an order using the Customers same post/zip code, but could not place the order.
What we did find out was if we used our Businesses post/zip code, as it is in the list above, we could get the available shipping rate, but then went into checkout and edited the delivery address to a post/zip code not in the approved list above and still got the shipping rate that only the above post/zip codes could get.
Can we stop this from happening, we need to stop this from happening.
