If you're referring to the "Amazon drop-ship" business, I think that space is probably already overcrowded. Those who got in and figured it out - and got a head start, probably still have an advantage. But you must realize that Amazon can, at their whim, change anything at any moment and kill that business. Plus you have unscrupulous competitors who will throw a little money in to buy a bunch of your products as soon as they appear (if your products compete with theirs), and then leave negative reviews. I suspect that eventually the only way to be a winner is to be a cheater. Surely you don't do that.
