I would not say that overpricing your shipping fee is at all unrealistic. You have the expense of the carton, packing material (bubble wrap or beads), time spent doing it, gas to and from the post office, etc.

If you were selling 100 items per day you could certainly reduce the excess shipping amt. If you are selling a highly competitive item like a computer Hard Drive, the customer will take into consideration your shipping charge anyhow when bidding on an item.

Since it is an auction you cannot be sure of the price you will get for your product. Some auctions vary for whatever reason.

I would never bid more than what I wanted to pay for an item + shipping anyhow.
