Nintendo has announced a pretty sharp deal for RPG-loving bargain hunters. If you purchase both Fire Emblem: Awakening and Shin Megami Tensei 4, and register them both with Club Nintendo, you'll get a healthy $30 in eShop credit on your account.
The Club Nintendo page has the details. You'll need to register both games sometime before August 31, through the included code in physical copies, or by linking your eShop and Club Nintendo accounts if you buy them digitally. Then you can redeem your $30 code from Club Nintendo, which has to be retrieved by September 30. The code can be redeemed for 3DS or Wii U credit.
Fire Emblem has been out for a few months. Shin Megami Tensei is due out next week, on July 16. The games themselves retail for $40-50.
