If you purchased an older HeroMart product sold at a ToysRUs location or via the ToysRU website and have an issue, you will have to contact ToysRUs directly for assistance. Since you did not purchase your item directly from HeroMart, we have no way to look up your order. We also cannot give you any in-game codes if they are missing or were already redeemed.
HeroMart did have a few items in 2012 sold at select ToysRUs stores in the United States such as the AQWorlds card game, the 2012 calendar and the Artix and Sepulchure action figures.
If you purchased your item from a ToysRUs retail store, use their Store Locator with the contact information for the store you went to. If you purchased your item from www.ToysRUs.com, here is their Online HelpDesk for further assistance.
