Package forwarding, also called parcel forwarding, is an international shipping service offered by shipping companies to international online shoppers who want to do cross-border online shopping. Package forwarding is becoming more and more popular among international shoppers because of the high growth rate of e-commerce websites and shipping limitations of most such websites.[1] Package forwarding service is provided by package forwarders to make cross-border shopping convenient and easy, getting rid of the problems in payment and shipping. A package forwarding service is different from mail forwarding. Mail forwarding refers to the mail in traditional meaning, or magazines or papers that are normally called mail, while package forwarding refers to online purchases or orders that are shipped within a bag or a box.
