I have a great idea on how a retail company could save money, help save the environment, possibly generate marketing info for them, create goodwill towards it's customers, and, it would cost the company hardly anything to get it rolling. Problem is I want to pitch this to my favorite drugstore first, since it was there that I got the idea. I went to the manager, and he was helpless, suggesting the company website, which didn't help. I'd call the company, but I do not know who to ask for. Does anybody know of a way to get a company's attention? Or how to suggest an idea to a corporation? Because if one place doesn't want this, I imagine another will.
Thanks for the help!

First and foremost get your idea with your name as inventor Do not discuss your ideas with anyone until that id done.Use a search engine to find who the CEO is and contact them again protect yourself. A lot of bad people out there especially when money is involved
