This method is gaining in popularity in recent years. It involves you being the middle man between a supplier of products and the buyer. There are many ways to do this. But without proper training it can be very risky. AKA you could loose a lot of money trying to be successful. As I live in Australia I have not attempted this method to make money online due to our population not really having the market the USA has.
FBA (Fulfilled by Amazon) is where you can buy products for cheap from a commercial supplier. From there you can ship the products to the FBA program by Amazon. You then list that product for sale on Amazon. com. When somebody buys the product from amazon they take care of the shipping for you. Amazon takes their cut and you keep the profits. A legit and profitable method, but it doe's have high risks for ill prepared people.
Ebay is another place where you can drop ship or use the arbitrage method of buying cheap and selling for higher. There area couple courses online which teach you how to buy from Amazon for cheaper and than sell on Ebay at a higher price. Sending the product directly from the Amazon store to the customer from Ebay's mailing address.
