Leave the energy drinks on the shelf at grocery stores. Seems like everywhere we look someone has an energy drink in hand. Most of those people pay $2 a can and I know many people who drink one everyday. But I want to be more on the conservative side and say that the average person who is on the energy drink wagon will drink roughly a couple hundred cans a year. I doubt that many of them are buying in bulk. So 200 cans at $2 a drink is over $400 a year. Even if you are buying them in bulk and drink one everyday that is over $350 for the whole year just for some sugar water and a fancy name.
