Here's the situtaion.

I found a product thru Ebay and very interested in stocking this on our site. So I contacted the manufacturer in China and we pretty much finalize the deal on doing an initial ordering to start up.

Beyond my knowledge, there is already another guy who is selling the same product and claim he is the main dealer in the US. And for some odd reason, he found out about my interest and then contacted the manufacturer not to do any business with me because he said that I am trying to undercut his business.

So now the manufacturer back out of our deal......

So what are my rights?
Is there is any, how do I go about pursuing this and will it be worth the effort?
