I see a big drop off in store traffic at the various stores I stop off at when I occasionally get a small cup of coffee.. After my wife got diabetes from drinking mochas everyday, we have pretty much stopped buying coffee at Starbucks. I still by the 2 1/2 pound bags of beans at Costco though. It saves me $140 a month.
I'm talking about the coffee drinks that they use sugary syrups to make. The mochas, the frapachinos ...etc. Those drinks are loaded with sugar, just like sodas. I also drink regular coffee, using only Starbucks beans.
