Try searching on ebay for a category of items such as iPads or what ever you want to sell and under the advanced search / refine search you should find an option for completed listings look at those and you can see what sold and what did not.

To know this first you have to see the trend and hot products at this portal, this will help you to understand which product is more in demand. You can also check queries of people that what they are asking on different portals.

I want to start selling on ebay and what to try a wholesale directory, but I don't know what products to sell that are in demand. Biggest fear is to be down on money and have products sitting n my house. I see people selling camera, TVs, etc. But it seems those products are even in demand consistently.
