Now here is all you have to do — Fill out the information with fake info and a disposable email address (for example Dodgeit or mailinator). Then submit, watch the pretty flash and see if you win. If you dont, hit the back button and change the email address and resubmit until you do. :D

3 Free Itunes

If for some reason you try and win this game, but don’t use Itunes, and want to donate your free code, you can send it to itunes@i-hacked.com and I promise to put it to good use!

Or, If you own a domain — set up a catch all email address and point it to a gmail account. Then create the following filter:
subject:(Colgate(R) Max Fresh(TM) Instant Win Game Confirmation E-mail) Do this: Skip Inbox, Move to Trash

Then only your winners will show in your inbox.. I have heard rumors that some people are having success with creating Macros using Macro Scheduler.. :p

After you win, go out and buy some Colgate MaxFresh with Breath Strips.. Because I didnt want to say anything, but your breath kinda stinks.
