sorry don't get it and tried to fix this with the istraxx-quantity plugin - but this seems only to work for products?!?
custiomer choose in one category:
9 * product A for 100% price
1* product B for a 100% price
but for 10 products the customer should get 10% off
but for 20 products the customer should get 20% off
but for 50 products the customer should get 30% off
Which meens: "discount per category"
Is this possible and anyone able to tell mehow to di this??
Thanks for help.
