Moreover, it's dead simple to make iced tea at home, brew a gallon of strong black tea (way stronger as you normally would for hot tea) in a big pot, leave it to cool with sugar (to taste) and pieces of fruit (apple, orange, lemon...), put in the fridge when cold.
Enjoy, whenever you want pour a ladle into a cup or fill a reusable bottle to drink on the go.
It's a cold alcohol-free bewerage like coke but seemingly healthier, that's not as boring as just a bottled water? I see how it can be popular on the street, from vending machines and shops when it's hot outside, but buying them in a quantity, for home, is beyound ridiculous imho.
