eBay is planning a "Buy It Now, Get It Fast" marketing campaign in early-to-mid December. Sellers may extend their holiday selling season by using Buy It Now (BIN), an optional and free enhancement to eBay auction-style listings. The BIN feature allows sellers to name a price at which they would be willing to sell their item to any buyer who meets the specified price. eBay also advices that sellers may want to consider offering expedited shipping, "because it has been proved that many buyers are willing to pay more for additional service levels in order to get their items faster."
