Only bundled products in order

Hi,

I have your plugin and a plugin to make invoices.

I want to make the invoice with only the bundled products.

The order is with the main product price and the bundled products with price 0 so my invoice is being generated with 3 products (main product – price total and 2 bundled products with price 0).

How to configure to make the order only with the bundled products and the price of them?

thanks,
adriana
