Get Heracross for Pokemon X and Pinsir for Pokemon Y via Special Distribution

   On the Nintendo Press website, they have announced a new release that is to come soon. Serial codes for Mega Pinsir and Mega Heracross, both level 50 with the mega stones will be distributed some time from now to September 17th.
The Pokémon Company International and Nintendo today announced that beginning August 13 in the United States and Canada, the Bug-type Pokémon Pinsir—normally only encountered in the Pokémon X video game—will be available to players of Pokémon Y via a special wireless Internet distribution. During the same wireless Internet distribution period, the battle-tested Bug- and Fighting-type Pokémon Heracross—typically only encountered in the Pokémon Y video game—will be available to players of Pokémon X. Fans of these powerful Pokémon will need to act quickly as this unique distribution is only available for a limited time, ending September 17.

The Heracross, a Y-version exclusive, will be available to Pokemon X players with the moves Bullet Seed, Pin Missile, Close Combat and Megahorn. A Pinsir will be available for Pokemon Y players as it was only available in Pokemon X. It has the moveset of X-Scissor, Earthquake, Stone Edge and Return.
Players who visit participating GameStop stores to pick up the code can also pre-order the Pokémon Omega Ruby and Pokémon Alpha Sapphire video games, releasing November 21, 2014, for the Nintendo 3DS family of systems, and receive a special pre-order bonus poster. Codes for the Heracronite and Pinsirite Mega Stones and the bonus poster are available while supplies last.
