Our app enables you to run pre-sale announcements and limited-time sales effortlessly. When products are outside their sales period, the "Add to Cart" button is automatically hidden, and it reappears during the sales period. You can also display unique messages for products before, during, and after the sale. As the first in Japan to utilize the Cart and Checkout Validation API, our app can prevent purchases of products outside their sales period—a scenario not covered by existing apps.

With this application you'll be able to use Early Bird as a shipping method for your customers to choose. The app automatically shows the shipping method if a customer enters a valid postal code where Early Bird does deliver. A real-time API call will be sent to Early Bird to determine if the postal code is valid for delivery by Early Bird or not. If the postal code is valid the shipping method will be shown during the checkout process, and if it's not Early Bird will be hidden from the user.
