As you can see below, I've entered the maximum discount possible which is equal to the amount of the postage charged.
However, whenever I try to subtract any discount in excess of the maximum postage amount of $2.10, this is the message I get...
Perhaps you'd care to enlighten those of use who are clearly too thick to work out for ourselves how to enter a discount in excess of the postage amount. I'm sure we'd all be eternally grateful (well, I know I would, because I've been trying for as long as I can remember and there is no way it will let me discount any more than the amount I've specified for postage).
I have never said anyone was thick, I am struggling to work out why you would say that 
I know you didn't say that and I'm not suggesting that you did. I said it because I am obviously too thick to work it out for myself.
You clearly said...
I certainly can - I had free postage on all my listings until recently, and I often get buyers who just want one card out of a pair for example so they buy and I refund them the savings via the invoice. I regularly did this with all my free postage items. I also used it to deduct larger amounts if someone missed out on a discount sale I was having so I wanted them to have the benefit. Just tonight I sent an invoice with $0 postage and $11 discount as they bought many items.
However, in the very next post I included images to show you exactly what happens if I try to discount or refund any amount in excess of the postage charged. And I'm not the only one. It is simply not possible to reduce the invoice to any amount less that the sub-total, so I'm at a complete loss to understand how you manage to do it when nobody else can, which is precisely why I said "Perhaps you'd care to enlighten those of us who are clearly too thick to work it out for ourselves".
So you see, I wasn't having a go at you at all. I was having a go at myself. And I'm still waiting. 🙂
