Enrico,
I am unable to send the URL…the entire site is not available to the outside world yet. I have attached the spreadsheet that is used however.
The products we offer are customizable which means we have to reconfigure the machinery and manufactoring processes for each product. This reconfiguration requires a one-time fee per order.
If the customer orders one custom item they receive the fee one time.
If the customer orders two separate custom items they receive the fee two times.
However, if the customer orders more than one of the same custom item in the same order they only receive the fee one time.
That is what I am trying to figure out how to do.
I am currently doing it in the spreadsheet by adding a Qty field to the calculator and setting the underlying simple product to single item orders only (removing the woocommerce quantity roller).
This gets the price I want, but causes woocommerce to only see a single item in the order which then does not calculate shipping correctly.
Any ideas?
