is there an easy way of applying for the success fee or do you have to email in each time, seems like a lot of work as I have only just realised that the success fee is taken on postage (the postage amount I charge no longer covers the  shipping because the success has come out)   I would have to go a long way back to work out how much I am owed on success fees as I always combine shipping, a lot of people buy more than 1 book at the time to save on the postage amount but hit the postage on each book then ask after the auction is finished
