You can find the low-hanging of the Japanese pop snacks (Pocky, Yan-yan, Koala's March) at any Asian market in a top 100 major US city; but you won't find, for example, limited edition Soda flavored Kit Kats or Meiji Wintertime Fuwafuwa chocolate or anything crazy cool like that.
That's where a service like this would shine, I reckon.
