On Bonanza, it’s free to open a store and list items. You only pay when you make a sale—Bonanza charges a small transaction fee (starting at 3.5%) that is calculated from your Final Offer Value. FOV = item cost + shipping fee x 3.5%.
You can also choose from 5 paid membership levels which offer a variety of premium tools and resources that can help you drive traffic to your Bonanza store. Prices for these plans range from $20 to $300 per month, though some levels are available with a free 30-day trial.
