Unless you want to be a distributor you are better off just paying the best price you can get and working more on things like promotions, advertising/viral marketing and customer service. If you have a retail shop you are competing with other stores generally buying the products at the same price as you. Price is rarely what drives retail sales, unless you are Walmart and I assume you are not. If you buy in bulk you can often negotiate with distributors but other than buying a boat and going to China, you have to pay regular wholesale price.

As far as trade shows go, wholesale distributors get better prices for bulk only and you can’t normally purchase products at a trade show (place orders, but not walk out with product). You generally get the same price if you call the manufacturer or the distributor.

If you can afford to buy that many,
and you have a big storage place,
and you are pretty sure that you can sell it all. The go for it. But remember, that bulk merchandise is a specified item that you want to sell. Do not mix. (for example, you can only buy Adidas shirt. No Shoes and purses and clothings.
