I have found Amazon to be an interesting place to source unusual/random/imported booze, snacks, coffee, soft drinks, bulk boxes of genuine Japanese instant noodles, imported chocolates/sweets…. You name it.
I’m interested to read what you have bought from there
Occasionally bought a crate but more often I would buy the powdered sachets, it’s great stuff especially when ice cold. There’s an asian supermarket near my work that stocks it so haven’t had to buy any this year.
