I've written about coffee several time but I believe that most of the stuff we drink here in North America is not pure coffee! They blend different things including chemicals and essences and sell as coffee starting $1.5 at least. Coffee companies, though compete to sell more of this coffee-like stuff on daily basis and as I said there are lots of them.
At the same time there are others who either are looking for fame or just doing a trail and error. Once it's said that coffee is dangerous because it causes brain stroke. In a week you here that they say coffee is good for prostate cancer! So what the hell? Am I supposed to drink the damn thing or not after all?
I personally only drink McDonald's but even that one was stopped by me. I save a lot now! I simply buy a can for about $6 and have it for a month or even more. Nabob is the one that I'm stuck to but I will change it as soon as I find a rel coffee, even if it's more expensive.
