Welcome to SaleHoo!
Actually for most wholesale site, their posted prices are not necessarily the "wholesale price". You with wholesale, the final price per unit will depend greatly on the volume of your order, so the ore you buy the lower the unit price goes down. Oftentimes it is best to make an inquiry directly to the supplier to get the real wholesale prices :)
Plus mind you, there are now quite a number of wholesalers on ebay!
