Sweet Arrows Consignment Events are held twice each year in the spring and fall in Rapid City. Consignors bring gently-used baby and children items to the event the day of the Pre-Sale. These items are prepped, tagged, and priced by the consignor beforehand. Consignors keep 70-80% of the items selling price and receive a check in the mail within two weeks after the event. Shoppers find great deals for quality items they need for their growing children.
