I use a code that adds a discount when choosing "Local Pickup" in the cart and at checkout.

/**
* Discount for Local Pickup
*/
add_action( 'woocommerce_cart_calculate_fees', 'custom_discount_for_pickup_shipping_method', 10, 1 );
function custom_discount_for_pickup_shipping_method( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    $percentage = 15; // Discount percentage

    $chosen_shipping_method_id = WC()->session->get( 'chosen_shipping_methods' )[0];
    $chosen_shipping_method    = explode(':', $chosen_shipping_method_id)[0];

    // Only for Local pickup chosen shipping method
    if ( strpos( $chosen_shipping_method_id, 'local_pickup' ) !== false ) {

        // Set variable
        $new_subtotal = 0;

        // Loop though each cart items and set prices in an array
        foreach ( $cart->get_cart() as $cart_item ) {

            // Get product
            $product = wc_get_product( $cart_item['product_id'] );

            // Product has no discount
            if ( ! $product->is_on_sale() ) {
                // line_subtotal
                $line_subtotal = $cart_item['line_subtotal'];

                // Add to new subtotal
                $new_subtotal  = $line_subtotal;
            }
        }

        // Calculate the discount
        $discount = $new_subtotal * $percentage / 100;

        // Add the discount
        $cart->add_fee( __('Discount') . ' (' . $percentage . '%)', -$discount );
    }
}

I also created several coupons. How can I change this code to exclude all coupons from the calculation when I select "Local Pickup"?

How can you show a notice that coupons don't work when "Local Pickup" is selected?

I would be glad to have your help!

// Add Percentage Discount to Local Pickup in Woocommerce

        if (0 === strpos($chosen_shipping_no_ajax, 'local_pickup')) {
            $discount = $cart->subtotal * 0.15; // Set your percentage. This here gives 15% discount
            $cart->add_fee(__('Discount added', 'yourtext-domain'), -$discount); // Change the text if needed
        }
    }

    if (0 === strpos($chosen_shipping_no_ajax, 'local_pickup') && !empty($applied_coupons)) {
        foreach ($applied_coupons as $key => $coupon) {
            WC()->cart->remove_coupon($coupon);
        }
        wc_add_notice(__('Coupon will not work for local pickup'), 'error');
    }
}

add_action('woocommerce_cart_calculate_fees', 'local_pickup_discount');

Tested OK with WooCommerce 6.4
