Shiva, Amazon also allows you to sell used items not just new items.
It's not that we support or approve of the fees charged by ebay. It's more like we understand the market place and the dynamics of supply and demand. We're fatalistic about what the seller can charge and what the market can bear.
For example, we can say in the USA that we find medical care costs to be outrageous yet we still pay them because if we don't...we'll die! Unfair? Yes. Profit-driven? Absolutely! But we'll pay them because we have no choice.
I'm guessing that Ebay just keeps raising fees until their traffic goes down, then lowers them. Technically Ebay doesn't even fix prices (price elasticity) but rather sets the cost of production for the seller. You'd almost have to look outside of economics and look towards game theory...specifically the Nash equilibrium (
http://en.wikipedia.org/wiki/Nash_equilibrium). Because basically Ebay wants to fleece you without killing you off so while they are looking to their own profits they must also give you concessions. I'm guessing for very large volume Ebay sellers their fees are low...probably extremely low...because they get a favored status from Ebay.
Personally I'd just hook the jacket on Craigslist and get cash. I've had a lot of luck selling stuff on craigslist for a very fair or even a good price.
Just to let you know I don't have a degree in economics or even studied it; it's just a passing interest in economics, statistics, and game theory. But my sister is an investment banker, my mother is a CPA, so I've picked up some stuff through osmosis. But I could just be bullshitting.
