How do I get any codes?
Just add the app to your wish list :)and then wait if the developers send you a code
Post asking for one, and/or send them an e-mail.
Another great site: appVersity.com. Check it out, just for posting a comment on any review your entered for a chance to win the app which was reviewed! Not to mention all the promo codes gave away in the forums!
