Posting and browsing items on OfferUp is free, and buying items with cash is free for both sellers and buyers.
Certain transactions, like shipped items, may include service fees or shipping costs when the item is sold. Any applicable costs will be shown to the seller when listing an item, or to the buyer when making an offer.
For vehicle listings only, sellers can list three cars and trucks per month at no charge. Starting with the fourth post each month, the seller pays a fee to list each vehicle.
