Heroes of Newerth is giving out $10 accounts at the moment. They are usually $30 and I think this is great value. I have been playing for a year now and still play regularly. It is an amazing game if you have time to understand the mechanics or are familiar with DotA/LoL.
Below is my referral link for anyone who feels nice. There are no extra steps for you it just gives me 500 coins in the game to buy some skins etc. I would appreciate it :)
