When you say "large amount" of products, really the price you will pay depends on the quantity ordered. It can also depend on the length of your relationship with the manufacturer.
Suppose, for example, we are talking about generic, non-branded HDMI cables. If you want 1,000 pieces, try AliExpress.com. 1,000 pieces is really not a large order to a manufacturer.
On the other hand, if you want 100,000 pieces, THAT is a different story. In that case, try Alibaba.com directly. Please understand that prices are not normally posted for quantities that large. You have to contact the manufacturer and negotiate the best deal you possibly can.
What stops most of us from going that route - myself included - is that we do not want to tie up a significant amount of money into one product. If something new takes it's place, we could end up stuck with inventory we either cannot move at all or must sell at a loss just to get rid of it.
Many times, we hear similar questions. For example:
Does anyone have a good wholesale source for iPads?
When we ask how many they are talking about, they want 5. Sorry, but 5 is NOT a wholesale order. At that quantity, you will get a discount off the normal retail price, at best.
It also depends on the type of product. Take a popular mass-market product like DVD players. Walmart and Best Buy often order DVD players in quantites of 50,000 or more. That is why they can sell them for less money than you could buy them for. Smaller players are usually better off focusing on smaller markets.
