Doug,
That sounds high but like someone else said I don't know how the auction was listed. I sell a lot on E-bay and always figure its going to cost me 10% of everything including shipping. Here is a link to the E-bay "fees" page. Looks like it should be 10% but don't know if you used any optional services like buy it now etc.
