Right!

Or use

$Vend::Session->{assigned}{subtotal} = $mynewsubtotal;

?

You mean

CommonAdjust  [my-usertag-for-the-new-item-subtotal]

? Would that not change the price ([item-price]) only? For example, 
would that not displays

sku  description    Qt.(Unit)  price   unit   item total
1234 soap           1          36.00 $  72     36.00 $

instead of

sku  description    Qt.(Unit)  price   unit   item total
1234 soap           1          0.50 $  72     36.00 $

?

It seems to me, my brain is down in the moment! :-(

Thank you!

Joachim
