I have no idea what this stands for

I know their are many companies on the stock market exchange, and they sometimes use just initials to identify their stock. I was wondering what CSTR stood for, and if it is possible it might be coinstar? But then again, it could be anything. I might think about buying this stock it does seem to be fairly hot lately and I know even I have used their machines. I did not know that I could buy their stock at all until someone mentioned the company name to me. I am going to go online and use one of the stock broker companies that advertise there.
