OK here's some data * The Item with shipping costs €42,00 with NO discount
* The commission module setting is set to handle discount codes at "store cost"
* The store commission is set "per seller" at 8% with €0.35 transaction fee for all sellers
* I created a Cart rule for 5% discount - shipping not included in the discount
Now proceeding on the checkout page:* On the cart the discount comes to -€1.20
Proceeding to Paypal here's what I get: EGGBAY €3,71
Commission
Items price: €3,71

SELLER1 srl €36,79

Items price: €24,79

Total €40,50 EUR
Now the same again with NO discount: EGGBAY €3,71
Commission
Items price: €3,71

SELLER1 srl €38,29

Items price: €26,29

As you can see the seller pays for the discount - the store doesn't.
I'm I doing something wrong or it just doesn't work....
