Hmmmm, I just made a post about niche product in the 'starting out importing' section on a question asked on title: 'Another Kiwi'.
Certainly niche products are falling out of the sky, but they can be found. But you do have to go out and look just a bit..
The main problem today is that everybody is so caught up in the get rich overnight on the internet theme, that no one is willing to go out and find these products..Everyone wants to look on ebay, see what everyone else is selling and turn around and sell that also...Then they wonder why there are no niche products and successful sales..
If you want to find your OWN niche product, the find a 'need and fill it'.
One of the easiest ways to find a niche product is to look and see what types of products are selling well. Once you have done that, then simply look at that product and see what would compliment that product. What would make that product more beneficial, what would be a good companion to that product, or extend it's life or usefulness..what would make that product stand out just a little bit more for it's owner,,things like that.
That's were you will find your niche's..The people who start looking at things like that, and thinking for themselves, will find that niche, but if you want to wait until someone else tries it first and then copying that, then you are going to be left in the dust..
