Today this article from the Wall Street Journal caught my eye not just because of the deals aspect but more from a pure business marketing aspect. Amazon is a monster in the same way that Google is. It has a ton of weight to throw around and it doesn’t mind doing so. It offers local deals in a few markets (Boise, LA and others) just like Groupon does. Amazon invested in Groupon’s biggest competitor. So what better way to pee in Groupon’s corn flakes than to go after their home market of Chicago?
