One of the easiest ways to start a business is by creating your store on online marketplaces. Well, selling from an online marketplace is not easy, however, you do not have to spend a lot of money to build your store as you can start for free or with a small investment. I sell on Amazon, Etsy, Redbubble as well as facebook Marketplaces. I generate more sales on Etsy than on any other eCommerce marketplace.
