The products you're interested in are some of the most competitive online. And yes, you'll find that these sell at wholesale prices or sometimes, below wholesale on eBay. That's just how intense the competition is. Unfortunately, to be able to compete, you're going to need to purchase in bulk quantities to drive the wholesale price down. That being said, may I ask if you have actually tried contacting the suppliers directly for a catalog and a quote or are you just going by the prices on the suppliers' websites? The best prices are never listed on the wholesalers’ website. A lot of suppliers will tailor their prices to your order. And another thing, some suppliers also have a retail arm, so it’s not uncommon to see retail prices when you visit a supplier’s site.
