Its all about money and profit mann. Like Oddworld only not sadistic
Though I think those methods are really pointless. They are the same drink the only difference is the name and sometimes the color. Its all part of the sceam of business. They are trying to get you to buy their product And simply they don't want to risk on their costomers getting bored with the same old thing. So they create a new slogan and a new qoute on qoute drink when all along its the same. They are just trying get you to buy more.
