Bidnapper is giving sellers an incentive to advertise its service to customers. Taylor Abercrombie of Abercrombie Online, which runs Bidnapper, said sellers can offer a coupon for 1 year of free Bidnapper service, a $49.99 value, to their customers or prospective customers, at no cost to the seller.

"In the competitive world of online selling, it is difficult for a seller to set their listing apart from their competition," Abercrombie said. "We believe this is a great way for seller to add value to their listing, and keep those customers coming back." Seller can generate a coupon to send to customers and learn more on this page.

Bidnapper is also running a promotion called "Switch to Bidnapper." Auction bidders who use a competitive offering can switch to Bidnapper and get 1 year of free service to try it out. More information about the promotion is available on this page.
