I got my Core Charge issues 90% fixed.. Where as we have an up charge for the parts core and refunded when they return it.
I have it set as a string and it adds $275 to your order in the cart..
Is there a way to have the $275.00 listed in the cart and invoice as a separate line.. I did a lot of searching with no luck

Looks like you're looking for your own solution :)
I was .. I got half way there.. I think I can deal with this now.. and just edit the invoice to break it down into two line items..
