4. What's the difference between affiliate marketing and dropshipping? Dropshipping is a method of selling that allows you to run an online store without having to stock products. You advertise the products as if you owned them, but when someone makes an order, you create a duplicate order with the distributor at a reduced price. The distributor takes care of the post and packaging on your behalf. As affiliate marketing is based on referrals and this type of drop shipping requires no investment in inventory when a customer buys through the affiliate link, no money exchanges hands.
