Often, the best prices are never listed on the wholesalersâ€™ website. Most suppliers will usually tailor their prices to your order. Someone ordering 20 items will get a much better unit price than someone ordering just 10, for example. Note that suppliers will also negotiate better prices with sellers that they have a good relationship with. If you haven't already done so, try to email them first to ask what the best possible price is that they can give you for the products you wish to buy.
You may search for the wholesale program link in the website, some requires a registration before providing wholesale pricing. For example if you look into Link hidden: Login to view it states
"Many items on our website are available for wholesale at reduced prices including all designer sunglasses. If you would like to stock anything on our website, then please contact us with your details."
Hope this helps. :)
