Thanks for the reply!

Just to be safe: The only thing this snippet does is remove the action that sends that particular email, correct? There are no other native WP-functions connected to this?

Does anybody know if set_price should be persistent?

Okay, now I have tried to run the minimal amount of code here in a fresh install with Storefront and no plugins.

foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
        $id = $cart_item['product_id'];
        $quantity = $cart_item['quantity'];

        if ($quantity < 3) {
            return;
        }

        //Split 1 of the item
        //Set quantity to quantity - 1 for the item
        $cart->set_quantity($cart_item_key,  $quantity - 1);

        //Get variation vars
        $variation_id = $cart_item['variation_id'];
        $variation = $cart_item['variation'];

        //Add the product as a new line item with the same variations that were passed
        $item_key = $cart->add_to_cart($id, 1, $variation_id, $variation, $cart_item);
                
        //Set the price to be free
        $cart->get_cart()[$item_key]['data']->set_price('0');
    }

If I comment out the return inside the if-statement, it works. I get three split items, of course, but it sets the price to 0 for all of them.

If I have this return present, it splits out one item like I want it to do, but the price is not set to 0.

If I log the price on the last line, my log shows the price is set to 0. Why then, does the cart not reflect this?

How does set_price work? Is it not persistent? Does it not set the price in the cart for the session in the database?

It seems the code execution has to reach set_price for each time the woocommerce_before_calculate_totals hook runs. But in this case, it won’t do that, because the quantity will only be >3 on the first run of the hook.

So it will reach set_price when in the AJAX-call that updates the cart, but it won’t reach it when the page reloads. If setting the price was persistent for the session, this should not be a problem.

How would you set the price of a dynamically added item like this?

Thanks!
