WooCommerce: Slashed Cart Subtotal if Coupon @ Cart

This is a nice snippet to let users know what the original cart amount was by slashing the cart subtotal and showing the cart subtotal after discounts on the same line (Cart totals > subtotal).

You can then hide the coupon code line if you wish!

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.

  1. I just want to say thank you for sharing all these useful snippets for free. I learned a lot on how to access WC objects, etc. from your code and your hooks reference pages. I was coding a big project and kept having to look up how to do X and Y, to which the answer seemed to always be, “just use this plugin!”

    No!! No more!!! Plugins just are bloat and want to give me stupid popups I keep dismissing to sell me crap I don’t want. I’ve become more confident in coding things for myself thanks to looking at these snippets so I don’t have to deal with that nonsense every time I need simple functionality. Thank you very much!

  2. Hi Rodolfo, very nice thank you! It doesn’t consider the savings from the bundles. A little update would be great 🙂


    1. Hello Marc, thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

  3. Hi rodolfo,

    Thank you for this snippet to display cart sub total at front end, Is there any way to do same at backend. When someone applied a coupon to order. its not displaying sub total. only displaying discount amount, tax and total amount after discount.

    Discount: $12.00
    Shipping: $0.00
    Order total: $12.00

    1. Hey Sunny, thanks for your comment! Yes, I’m sure this is possible. The function would be similar but you need to find the “hook” that corresponds to the order total in the admin 🙂
