One of the easiest online businesses to start is an online store.  There are literally dozens of options online for your online store, and for the products you’ll stock and sell in your store.  There are also merchants who will allow you to set up an online store, and for a percentage of your sales, they’ll stock the products, handle customer service, and ship items to customers as they are sold. 

Perhaps the best place to learn about an online store front is to start a Zlio shop.  Zlio is a free community where members start their own shops, choose the products, and promote them, but where the actual merchants whose products you offer in your shop handle ordering, shipping, and the money for you.  And, the best part is, it’s free.
