> Why don't American's use an "and" here: Doing so is still standard American English. However, headline writing in particular has a tradition of extreme brevity, and this style leaves out conjunctions and adjectives (including articles). As another example of ambiguity, the article title here isn't explicitly clear that Amazon must remove these items from its marketplace. Read literally, "from US marketplace" could imply (somehow) the entire United States retail environment.
