I know things like this have been posted in the past, but I want a little bit newer list here.

I'm wanting to send my friend a box of snacks and drinks and candies, but we aren't really sure what's available here and not there besides a few things- most of the lists I'm finding just mention the same few snacks, and I know that isn't the case.

What American treats do you absolutely want to try, that either you can't get there or are extremely expensive due to import costs? What should I avoid sending?

If it helps, I'm in the Midwestern US (Missouri) and he's in Melbourne.
