As two of the most popular sources of suppliers, Worldwide Brands (this Worldwide Brands review explains the directory in more detail) and Ali Express are close competitors – but the services they offer are very different when looked at in detail.
Worldwide Brands is a basic directory of certified suppliers – it's not very functional but it does have a very large amount of contacts. This, along with the fact that all their suppliers are certified, are it's key advantages – there are more than 7,000 verified wholesalers and drop shippers and more than ten million curated products available to buy from Worldwide Brands.
Worldwide Brands membership costs $299, but there are discounts available – and it comes with extras including forum membership and 'how to sell on eBay' tutorials.
Ali Express is different to Worldwide Brands in two ways – first of all none of the suppliers are researched or certified and so there is no guarantee that they are safe to buy from.
Secondly, you are able to buy from any seller through the Ali Express site. That makes buying through Ali Express much easier than Worldwide Brands.
Although Ali Express is much easier to use and has more products to buy than Worldwide Brands – it lacks two key things that make Worldwide Brands popular.
With Worldwide Brands all the suppliers are verified as safe to deal with and as they are mostly based in the USA, shipping is much faster with WWB than Ali Express.
