I have one for $100 of free ads that I can't use since I already use adwords. If you don't already use adwords I will be happy to give it to you just PM me. You have to be a NEW adwords customer to use the code. Google will even help set up the account for you if you call them. If you haven't done adwords before make sure that you have some way to track how effective this is for you. To have $100 of free advertising but not know if or how it works is just a waste of your time. Google Analytics can help with that, along with Goal tracking.
