Like most auction houses, we do charge a Buyer’s Premium. This is a small percentage of the selling price that is added to the purchase price of each item. The buyer’s premium for each auction is stated on that auction page and in the online details for each auction. The Ohio sales tax of 8% is added to the purchase price including the buyer’s premium unless you have a valid tax exemption number. If so, please make sure we have it before the end of the auction in which you are bidding so we can make sure there’s no tax on your invoice. If paying through LiveAuctioneers your tax exempt form is submitted to them.
