I had a roommate in college who read an article about that and went on Amazon and bought a pound of caffeine powder. Not sure of the thought process on that one

  Scarcity bias. You know the limited offers that make you buy useless stuff just because you didn't want to miss the opportunity. Same idea. We instinctively place higher value on stuff that is perceived as scarce. It means that your roommate viewed that soon-to-be-banned caffeine powder as more valuable than it really is. Needless to say, that effect is a marketing classic.
