It's completely free to post an item for sale on HopUp. When your item sells, the fee is 7.0% (transaction fee) + 3.0% (payment processing) of your listed price plus shipping (if you selected to charge the buyer for shipping). The minimum fee is $1.99. HopUp pays out to the seller when the sale is completed (read more about payouts).
When are fees deducted?
Selling fees are deducted before we pay out to you for a completed transaction. The amount shown in your seller account represents your earnings after deducted fees.
There are no fees for cancelling a sale on HopUp. However, transactions you cancel will show in your public profile reviews. Only a seller can cancel a sale. Consistently cancelling will result in account restrictions.
