Hi,
(netto prices are displayed twice)
I probably still haven't understood you correctly.
The fact that the netto price appears twice is only because the multiplier is 1. If as in my example, 2 black organic cotton T-shirts size XL would be ordered, in checkout will appear, the price (excl. tax) and the price multiplied by two (excl. tax). See image:
But the green frame in my picture is supposed to be the brutto price not subtotal netto price
So is that a labeling problem? Is that better?

Could probably be solved with a language override ...
For example:
viewtopic.php?f=44&t=61034
Kind regards,
Benno
