"Used goods are very profitable but the real money is in new goods."
This was a question I had been thinking about for awhile as I have seen a number of courses talking about how one can make money getting used products from various sources and selling them elsewhere for profit. However, my concern was how one could consistently get product in this way and so believe it would make it harder for you to get consistent profit through these means as you are only as good as the size of the second hand market. The second concern I have is how you are able to build up any brand or stable business if your product can change based on what is available in the second hand market.
So my question is what do you folks think about this statement? Do you agree with it? Disagree? Is this a case of weighing short term game with long term stability/gain?
