Searching for and making contact with reliable and low priced wholesalers can be tricky – there are a large number of wholesalers across the USA and the world, and not all of them are of the best quality, but when you find a good one it can be worth it's weight in gold for an online business.
One of the easiest ways to find and compare wholesalers is to join an online directroy – like Salehoo, Doba or Worldwide Brands.
They each list the top wholesalers and provide access to a database where you can search for a supplier (either a wholesaler or drop shipper in the cases of Salehoo and Worldwide Brands) by product name, keyword, category, etc. They also check each of the wholesalers before adding them to their databases – to make sure they are reliable and legitimate, so you will never need to worry about scams.
Please refer to my worldwide brands review here for more information about WWB and the alternatives, like Salehoo and Doba.
The only downside is that to join you need to pay a membership fee. Salehoo costs $67 a year, Doba is $59 a month and Worldwide Brands costs up to $299 for lifetime membership.
If you are setting up an online business though, that could be a worthwhile investment.
