I paid 0,85€ for that one in a usually quite expensive supermarket, so it might be cheaper elsewhere.

If you're looking for a single portion drink, it can be one of the cheapest options. Of course a ≥1l bottle (¼ gallon) is cheaper per liter, but that's not the point.

both are sugary drinks with a low amount of actual fruit juice.
