Make discounted price appear in Cart and Checkout Page

Hello,

Sorry to say there are no options in theme settings available for that. This requires customization, which is beyond our support policy.

I have searched for a possible solution and found a custom function that you can add to your functions.php file. I have tested this code on our test site, and it is working fine.

If the provided code does not work as expected, unfortunately, we are unable to modify it further.
Add this to your theme’s functions.php file of the theme.

add_filter('woocommerce_cart_item_price', 'pk_cart_price_display', 10, 3);
function pk_cart_price_display($price_html, $cart_item, $cart_item_key) {
    $product = $cart_item['data'];
    
    if ($product->is_on_sale()) {
        $regular_price = wc_price($product->get_regular_price());
        $sale_price = wc_price($product->get_price());
        $price_html = '<del>' . $regular_price . '</del> <ins>' . $sale_price . '</ins>';
    }

    return $price_html;
}

// Show sale and regular price in mini cart
add_filter('woocommerce_cart_item_subtotal', 'pk_cart_price_display', 10, 3);

Hope this Helps!

Best Regards,
