When it comes to any of my past or current consignment accounts it has always been a percentage. In my experience the percentage has ranged from 25-40%, and sales have always come out of the stores end as stated in the contracts. All my contracts have had the sale info right in them, only ever had to mention it to 1 of my store. I would have never thought of the sale stuff myself but it was already in the first 3 contracts so made me think of it when my 4th didn't have it.
