Both of the top online directories – Salehoo and Worldwide Brands – are for paying members only, with fees ranging form $67 up to $299. That may sound unappealing, but the reason they can charge so much is that they only offer certified suppliers – wholesalers and drop shippers that have been researched and are guaranteed to be reliable and legitimate. When you're looking for new suppliers, having a list that's only the best ones means that much of the important work has already been done for you.
So, when you're ready to find a new supplier, simply log in to either Salehoo or Worldwide Brands and search for the product, category or supplier you're looking for by keyword. A list will come up, like searching on Google, but with some extra options – including selecting the country the supplier must be in, or whether or not they drop ship.
Then you only need to contact each supplier directly to start trading with them. Unfortunately neither Salehoo nor Worldwide Brands allows you to buy form suppliers through their sites (unlike Doba, DHGate and Ali Express), but that's not necessarily a drawback. When you get to contact a supplier directly you can build a good relationship and negotiate down prices, or get special discounts.
