What would having US$1.2 billion mean to you? If you're wondering why we're asking, check out the story of Tony Hsieh - the founder of Zappos. He started Zappos as a small, drop-shipping business selling trainers online, and sold to Amazon for US$1.2 billion just 10 years later.
With a drop-shipping business you set up a website that promotes products, but you never have any inventory to worry about.
Instead, when an order arrives you let your wholesaler know, and they ship the product directly to your customer. You have all the perks of running a business selling physical products, but without 99% of the headaches that can come from handling the inventory yourself.
