WooCommerce : How to make free shipping the only option
If you ever come to situation where you need to make “Free Shipping” as the only shipping option when your total cart total is more than a set amount, then this post will provide you some insight or idea.
For example, you set amount is $50. If user cart total is more than $50, then apply free shipping only.
Step 1: Open your functions.php file at your current theme folder (wp-content/themes/[THEME]/functions.php) You can download functions.php file from FTP, edit then upload again, OR you cab go to WordPress Admin -> Appearance -> Editor, and click functions.php to edit then save.
Final Step: Save the file above and done. You’ve told WooCommerce to remove all other shipping options (flat rate, internatinal delivery, local pickup and local delivery) when cart/order total is over $50 and apply free shipping option only.
