You may be charged an insertion fee when you list an item on eBay. (If you choose additional listing features, additional listing fees may be charged.) Then, when your item sells, you'll be charged a final value fee. See the fees for selling on eBay.
It depends what you're comfortable with: selling to the highest bidder or offering a fixed price. Learn about selecting a selling format.
Selling with Best Offer If you're listing a fixed price item, placing a classified ad, or selling on eBay in the Motors category, consider using the Best Offer option to let buyers negotiate the price with you.
