How do I use the Shopify Shipping app to calculate and display shipping rates on my store?

To use the Shopify Shipping app to calculate and display shipping rates on your store, follow these steps: Install the Shopify Shipping app from the Shopify App Store. Set up your shipping rates in the app. You can set up flat rate shipping, weight-based shipping, or real-time carrier-calculated shipping. Connect your store to the app by following the prompts in the app. Add your products to the app and set up your shipping rates for each product, or set up default shipping rates for your entire store. Enable the shipping calculator on your store's checkout page so that customers can see their shipping options and rates at checkout. Test your shipping rates to make sure they are displaying correctly on your store. If you want to offer free shipping or flat rate shipping to your customers, you can set that up in the app as well. That's it! Once you've set up your shipping rates in the app, they will be automatically displayed to your customers at checkout.
