Remember, wholesale suppliers don't usually post their wholesale rates for everyone to view. You may need to contact them directly as wholesaler suppliers won't be able to give you an accurate price until they actually know what sort of volume you want to purchase. Most wholesalers will have a set structure in place, pricing per unit type of thing, but not all do.
It's always best to talk with them for the prices, and let them know what your requirements are in regards to purchasing volume and they will happy to provide you with pricing based on those requirements, and also so long as the minimum order quantities set by the supplier are met.
Hope this helps.
