If you're planning to jump on the 'sock trend' make sure you find suppliers from sites like Salehoo or Worldwide Brands, where they have been researched and certified before being listed.
Certified suppliers are much more reliable than wholesalers or drop shippers that have not been screened or checked at all, and with Worldwide Brands they are also guaranteed too.
Where are the certified suppliers hiding?
There are thousands of them, but they are nearly all in members only directories like Salehoo and Worldwide Brands – which unfortunately require you to pay for access.
Worldwide Brands is the most expensive, but also the largest by far, at $299 for lifetime membership. The good part is that's a one off fee, and there are no hidden costs, but it's still a lot of money and I would not recommend joining unless you can easily spare the cash.
Salehoo is initially cheaper, at $67 per year, but that adds up to more after about 5 years of membership. Salehoo is a smaller directory, but it's easy to use and might be better for beginners to online trading.
The good news is that as socks are such a popular product now, both these directories – and free alternatives like DHGate and Ali Express – have a large number of them available at trade prices.
