Unlike the joy that comes from giving or receiving a gift during the holidays, making a return and paying for shipping can be a drag. But it doesn’t have to be that way. In fact, a recent survey revealed that one of the best ways to turn holiday shoppers into repeat customers is to offer free return shipping. For many retailers, it is a missed opportunity. In the survey done by shipping retailer Shippo, 54 percent of consumers said that free return shipping is important to them and is a decision factor when comparing different merchants.
