It's not always possible to obtain the postage cost until after the auction has ended. A few times I've been told that the item will have to be packed & a quote obtained before they can tell you the cost.
I can understand charging for (new) boxes & packing materials, but I've never understood these "handling" fees. I think thats just pure tax free greed.
If it took me half an hour to pack a horn, I certainly wouldn't charge anyone for the privilege. I wouldn't think my time was that valuable as to charge someone for it, especially when I know I'm getting a better price for the item than I would anywhere else. If my time was that precious & packing was such a strenuous hassle, I'd list the item as pick-up only.
To me that's like advertising a machine in the local paper for $100, but then wanting $120 from the buyer because I want to charge him for the time it took me to answer his phone call & show & demonstrate the machine when he came to look at it
