Are you sure you're understanding correctly? Most suppliers do not put their wholesale pricing on their website for the general public to see if they did everybody [retail customers:7dd6fe05] would want their items for that price.
Let's break down the distribution layers that most companies follow to give you a better example.
1. Manufacturer.--- The manufacturer are the people who make the product. You can buy from them, however, you are going to need a business license and a decent bank account and cash flow. [Truest form of wholesale prices:7dd6fe05]
2. Distributor/Wholesaler.----- They get the products from the manufacturer and break them down into wholesale orders, and some drop ship. They mark up the prices a small fraction from their cost from the manufacturer in order to make some profit. [Wholesale prices:7dd6fe05]
3. Drop shipper.---- They don't really deal in wholesale perse, they buy from the distributor/wholesaler in bulk and drop ship them for you. They mark up the prices a small fraction from their cost from the wholesaler in order to make some profit. [Psuedo-wholesale prices:7dd6fe05]
4. Your website/place of business.---- You set the prices, you may chose to do full MSRP, or slightly below MSRP. [Retail prices:7dd6fe05]
Ultimately you're only going to get the true wholesale price directly from the manufacturer of a product, but they DO NOT work with a sole proprietor nor small company, they only are interested in supplying huge chains such as Walmart.
I've gone through the sites that Irene posted, some are listing RETAIL pricing NOT wholesale [I explained why in the begining of this reply:7dd6fe05]. Some are listing wholesale pricing, and the ones that are, are not expensive. I don't know what prices you're expecting from a wholesaler, but those are really decent prices an can allow you to have some decent profit margins.
There's no such thing as a 100%+ markup in profit margins in business, ever, if someone does they either manufacture the product themselves and sell it to retail customers only and thus making good legitimate money, or are the shady type who overcharges customers and thus deserves to go out of business.
