The 'discount' that its calculating here is the difference in 'price' (Market price) and list price (online price). I can't see where it pulls in the discount value and makes a calculation based on this.
I was talking about
1. flagging an item 'Available for global discount',
2. setting the global discount as a provider to a percentage value
3. then hoping to see it affect all the items price from step 1.
Maybe its not possible
