I have juice boxes available. They don’t hold up under ice, but I keep them in the fridge. They’re the larger size (7.5 oz or something like that) Hawaiian Punch and I sell them for $1. Don’t sell many during the week, but easily go through 10 or more on a Saturday. I also have real lemonade I serve in cups, and that seems to be popular among the kids. It’s also surprising how many families pay $3 for an IBC root beer float (I have an ice cream freezer) for each of the kids (and usually parents too).
