Do you have to be 21 to buy drink MIXES?!
Answers:
No, only if it has alcohol in it.
If there's no alcohol, it's game for anyone. I used to buy margarita mix and mix it with 7-up and put it over ice. It was good! That is, if you like lemon-lime!
No, because technically they don't contain alcohol.
as long as there is no alcohol content you could buy it when you were five.
Anything with alcohol in it :O
Sorry :P
