I know it sounds crazy. i was trying to search for the app to handle my requirement but i found none of them. i was trying to duplicate their settings for postcode inventory from https://www.jayagrocer.com/ . Everytime i search for the postcode the system will tell me whether they support the area for delivery and also location name will be shown on top left corner of the site. At the same time, i noticed they also pull inventories from that supported postcode location. Postcode i search ('47800','59200','63000') to test the postcode checker.
