According to this:
When you list an item on eBay, you may be charged a listing (or insertion) fee. If applicable, you're charged one insertion fee per listing, per category, regardless of the quantity of items.
Final value fee
If the item sells, you're charged a final value fee. Final value fees are calculated based on the total amount of the sale and are charged per item.
Why did you not first look on eBay's site for this information?? Just curious.
