There are many people selling physical products on Facebook to make some money online today. You've probably seen those.
However, those are probably the lowest level of eCommerce where the business is not even close to semi-automation.
Before we get into this, let me explain the definition of physical products here:
They can be clothes, electronic stuff, supplements or even food. Basically, products that you need to be shipped out and something that the consumer "use" (not consume like an info-product).
It's now extremely easy to start an e-Commerce business because not only that there many products you can pick to sell and the availability of dropshipping services, there are many platforms to help you get started with no experience at all. These include Shopify, Amazon, Teespring, Lazada, etc.
