Compared to what?
My second best venue is Bonanza. I make about one sale a month there. Fees run about 50 cents a month.
That's expensive, because I have to go there every month or so and delete the 60 to 100 items I actually sold on eBay during that month. (I cross post from eBay to a few other sites). About an hour's work for a $10 to $20 sale.
Your costs should be about 20% of your sales. If it is higher there is something wrong- not with ebay but with your business model. For example, because some fees are flat rates, it is too expensive to list items that sell for less than $10. Because there is a monthly charge for Stores, it is too expensive to have a Store if you have fewer than 54 unique items in it.
