Yes, Tophatter does offer reserve pricing in _select categories._
Some products on Tophatter may be eligible for a reserve price feature. Reserve pricing would require that bidding surpass a specified reserve price in order for the product to be sold.
Eligibility is based on several factors and not all items or categories will be eligible. If a lot qualifies for reserve pricing there will be a Reserve Price field next to the product on the Seller Products page.
Keep in mind that if there is no Reserve Price field, the product may sell for less than the cost basis, or Target Price. For that reason, it is important that the Starting Bid is filled out correctly.
