In order to add a shipping method in WooCommerce, you must first go to the Shipping tab in your WooCommerce settings. From there, you can add a new shipping method by clicking on the Add Shipping Method button.
Once you have clicked on the Add Shipping Method button, you will be given the option to choose from the following shipping methods: Flat Rate, Free Shipping, Local Pickup, and Table Rate.
If you choose Flat Rate, you will be able to set a flat shipping rate for all orders. If you choose Free Shipping, you will be able to set conditions under which free shipping applies.
If you choose Local Pickup, customers will be able to pick up their orders from a specific location. Lastly, if you choose Table Rate, you will be able to set different shipping rates based on the destination, weight, and/or price of an order.
After you have chosen your desired shipping method, you can then configure its settings. For example, if you chose Flat Rate as your shipping method, you would then need to specify the cost of shipping.
Once you have configured the settings for your chosen shipping method, be sure to click on the Save Changes button at the bottom of the page in order to save your changes.
