Even in brain dead Cook County the population rose up against the one cent per oz tax. I was not much of a pop drinker but immediately went into DuPage County and bought a case.
The Central Committee had to rescind it within months grumbling all the while about “the children.”
I’m not sure what taxes are in East TN (apart from general sales taxes), but 2 liters can range anywhere from $1.00 to $1.79. I might not want to pay an extra 34-51 cents, but I usually don’t want to go to the trouble of going to another store just for soda. If it’s $1.34 at the $1.00 place, I’d probably pay it. If it’s $2.30 at the $1.79 place, I’d skip.
On the other hand, 12-18 cents more for a 12 ounce can or 20-30 cents more for a 20 ounce bottle (say at a gas station, where they’re already almost as much as a 2 liter in a supermarket), I would probably choose to not buy.
