[bivenator]

I work for a cardiologist as an independent contractor. I have enjoyed my time here and could not ask for a better enviroment or relationship with the Doc. I have not asked or recieved a raise during my 6+ years. My field is struggling and jobs are scarce so the pay i recieve is about market value.
At a conference over the weekend I found a vendor that could supply our drugs for a cost difference of almost 25K per year less than our current contract.
I have found myself in similar situations in the past and made the recommendations that would then pad the bottom line of my boss. I would not see any grease from my suggestions.
Is it wrong to try and get some money for my input? Do I go to my boss or try to strike a deal with the vendor? Is this a kickback/legal/ethical.
