In most situations any prices listed as a per unit price will not be wholesale. Buying wholesale means buying in volume, and suppliers will not be able to provide you with a price until they know what volume you will be purchasing in.
If you are looking at prices based on X amount = $Y, then they will be MOQ wholesale amounts.
You have to watch out when comparing what you perceive to be a retail price in another store. The product may be being reduced to clear, it may be on special or there may be other factors at work that will explain the product is in fact cheaper than buying from the supplier themselves.
Easiest thing to do, just contact the supplier and discuss your requirements with them. They will then be able to provide you with a clear price.
