I overheard my wife talking to a homeschool mom that raises and sells a certain type of dog (a registered breed of some kind) ranging from $1,000 to $1,800. I also know a couple teens that started a bread business where they sell the product at the local famer’s market and local stores. The product(s) have been so successful, most of the family has been involved in it.
The basic idea behind an online drop shipping business is that, as a small business owner, you don’t have to maintain a large inventory (or any inventory whatsoever) of products or handle any delivery to your customers. That eliminates the financial cost and risk of having a warehouse full of stuff you might not sell, and the hassle of arranging to send orders all over the country or the world. In fact, you don't have to manufacture or store any products at all.
