The problem with most wholesale operations is that you have an additional mark up in there. If XYZ wholesaling finds a manufacturer of a product, they have to sell it to you, and you have to sell it to the market. Often, you are now either not priced competitively or you are selling what everyone else is selling.
What you want to do is find `proprietary` product. Get it right from teh manufacturer or from a company that offers exclusivity in this country or region.
While it`s true that many firms are not crazy about dealing with web-only accounts, you have to go to them with more than just a whim to sell their products. Show them HOW you will market their products. Why your marketing is effective...or different! What advantage will they have by selling thru you?
If you can show a manufacturer that you can be a viable, effective partner then they would be fools not to sell thru you.
