That is the Amazon Grocery listing for it.  I searched for it in "all departments" and found it.  I thought you got "real" Hawaiian Punch, though; not the artificially-sweetened powder.  Now I'm conflicted, as I avoid artificial sweeteners in the off chance that they 
do cause heart arrhythmia (my heart's struggling enough as it is!).  But this could be a rare treat, right?
My reason for wanting Hawaiian Punch is for a mixed drink.  Roughly:
- 2 parts Hawaiian Punch
 - 1 part sour mix (more or less to taste)
 - 1 part white rum
 - serve over ice
 
It is dangerously drinkable, especially through a straw. Originally, my recipe included Mountain Dew, but I decided it wasn't really necessary (which is good because you can't get proper Mountain Dew over here, anyway!).  But you could maybe add a bit of sparkling lemonade for fizz if you want, though that all seems to have artificial sweeteners in it, too, these days.
I will invoke the decision bot:
!decide: buy the Hawaiian Punch packets, don't buy the Hawaiian Punch packets
