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 price and showing the price after the discount on the same line (subtotal). You can then hide the coupon code line if you wish ๐Ÿ™‚

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme 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 free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked 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 on PHP 7+.

  1. Hi Rodolfo, very nice thank you! It doesn’t consider the savings from the bundles. A little update would be great ๐Ÿ™‚


    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!

  2. 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 ๐Ÿ™‚
