It seems like everyone who has a supplier is never willing to share them. I've seen hundreds of posts of people boasting how great their connect is but when you ask them anything about them they act like its treason. I thought the Salehoo forum was about gathering together to find sources. There are millions of people selling online anyway so its not even like the few people who you help on Salehoo will put you out of business. I just think the Salehoo forums should be about helping each other and not just a place where people ask if suppliers are fake, because almost all of them are.
To be honest, it's not so much about the supplier, you need to find the right market in my opinion.
If you can find the right item to market, then you will be able to find the right supplier.
I know there are a few here that have spent a long time finding their supplier, but I seriously doubt in today's online world if there are any hidden suppliers out there that most of us don't already know about.
Most of the problems arise from the products people set their focus on!
If you want to find a unique supplier, I would suggest you start looking offline. That is where all the suppliers, and new products are hidden from online view.
Don't forget, if it's not online yet, it doesn't mean it doesn't exist. There has to be all sorts of suppliers and creative new cool items that are not yet being marketed online, the real secret is locating them.
Take a look through a local craft market for example, I am willing to wager that you will find hand made items not available online. Who knows, that unique product could be the next big niche online market, and you would have access to the only supplier.
