If I was paid to promote PiggyMojo, I'd be a ga-gillionaire. Unfortunately, I am not. I'm a fan, nonetheless.
PiggyMojo makes the concept of spending less money equal saving money. In, Dumb Marketers or Dumber Consumers? I explain how spending less money is not the same as saving money UNLESS you actively set aside the difference 'saved' (i.e. not spent). Well, thanks to a bunch of really smart people and technology, spending less literally translates into saving money.
See how it works...
