Sunkist Lemonade Diet

Diet sparkling (carbonated) lemon soda. Think 7up but more lemony and less lime-y ;)  I know the original seems to come and go, but luckily for those who love it, the diet appears more predictably. I have one box I found, purchased back in November 2016, which is definitely past it's "freshness", but if someone is interested, it's here!    Update: it sold within 10 minutes
