If you search online you'll come across a multitude of suppliers claiming to sell wholesale. SaleHoo only accepts genuine wholesalers, drop shippers, manufacturers and liquidators who have been online for more than 2 years. You can see this information for a specific website by doing a whoisdomaincheck, and it shows that digitradeonline.com is based in China, created just last year, Sept. 2011 Link hidden: Login to view
We also require a domain-based email address (not just a free hotmail account), a physical address and a landline number. We only accept suppliers offering safe payment methods such as PayPal and credit card. I'm afraid this company fails all of these standards and hence we do not think they would be safe to transact with. (Besides they also claim to supply Apple products).
If you let us know what specific dj gear product you need suppliers for, we will do our best to help and search for suppliers you can use.
