Although your intentions are clear, still I think that that too many links from a single domain can harm your website rankings. 
There are various strategies you can apply: 


If the back links are coming from a dealer's selling items page, is
there any way that you ask him not to use your link any more? 
You can start creating some more relevant back links to your website. In this way your back links will be diverted. Remember back
links diversity is very important. 
Don`t know if you are able to do, if the link that you dealer is using has nothing to do with the website and he is just using as the promoting item, this is called a bad link. Removing bad links is better than creating some junk back links.


I hope this will help!

I have a video html5 tag embedded on page. I need to trigger an action when the user clicks the "Play Button". But I can't find how to bind that to my action. Is there an event for what I need? I'm using jQuery...

Thanks!
