Hard to give a definite answer for this because I have started and run several different online businesses. It really depends on what you are selling and how much you are putting into it.
You can make anywhere between $100 a month to a very successful business where you are hiring hundreds of people to keep it running. For example, on the high end of the spectrum there is a company called Wayfair which is almost completely drop shipping and last year they grossed a total of 1.1 billion in Full Year Direct Retail Revenue. So, essentially you can make as much as you’re willing to put into your online business and our courses are the best way to achieve your goals.
