How do i add extra charges to checkout

[gajera-harsh]

I want to add additional charges for each delivery date that the user selects. How can I achieve this? I am building a checkout UI extension. Could someone please help me with a solution?

Hello @gajera-harsh,

"Stellar Delivery Date & Pickup" is an app that lets customers choose delivery dates and times. You can add charges based on the selected date by customizing and integrating the app with your checkout process. Follow these steps:

1. Install and Configure the App:

   • Install the 'Stellar Delivery Date & Pickup' app from the Shopify App Store.
   • Configure the app to enable delivery date selection. Set up your available delivery dates, times, and any initial settings.

2. Set Up Additional Charges:

   • Navigate to the app settings and locate the option to add additional charges based on delivery dates.
   • Define your charges for different dates. For example, you might charge more for expedited delivery dates or weekends.

3. Enable Custom Charges:

   • Use the app’s customization options to set up rules for additional charges.
   • Map these rules to the corresponding delivery dates, ensuring the charges are added to the order total when a specific date is selected.
