The strategy somewhere (google?) where they charge or otherwise disincent consumption of unhealthy food and encourage healthy food is kind of interesting.

My beverage of choice is Ito-En bottled green tea. I'd prefer if it came in glass vs. plastic bottles, though, and it is $1/bottle even at Costco, so at home or office I tend to just make my own using either matcha teabags (also from costco) or looseleaf green tea.
