Comma before OR in a list
The question is more or less in title: Should a comma be used before the conjunction 'OR' in a list of three or more items? I generally use the Oxford comma before 'AND'.
Hello @norwegianblue. Oxford commas are used in this way. There's a little more information available here: https://blog.oxforddictionaries.com/2015/01/21/video-oxford-comma/
