Hi Reef and welcome to SaleHoo,
Glad to hear you're enjoying our educational resources for online sellers. In regards to your question, our directory is really just an introductory to suppliers that we have personally verified and that may suit our members buying requirements.
You will find their contact information there, so from there you can make contact with them and discuss your requirements with them. Some will have their own websites for you to view, but I would always recommend anyone contacting any of our suppliers in person as you won't just be able to discuss your requirements with them, but you will get a good feel for their level of customer service in dealing with you, and it's important to deal with a supplier that not only has the right products at the right prices, but one you can rely on in times when you need good customer service to assist with any problems.
