In late September, The Pokémon Company and Nintendo announced a joint promotion with GameStop. Through October 15th, Shiny versions of the legendary mascots from Pokémon Scarlet and Violet are being offered at physical GameStop stores in the United States and at EB Games outlets in Australia and New Zealand. Involved stores in additional nations such as France and Japan were also included in the campaign.
Initial Problems and Supply Issues
Nonetheless, the giveaway faced difficulties from the beginning—Pokémon fans stated that their local stores had exhausted their code supplies in the period before the event. Now, about halfway through the giveaway timeframe, GameStop has replenished the codes, but it's likely your local store has depleted its stock again.
Because of high demand, the initial batch of complimentary Shiny Koraidon and Miraidon codes went very quickly.
Saturday, October 4th, the retailer announced a replenishment of codes via social media. The company's statement noted that they had worked with Pokémon's creators to provide additional codes, but there's a catch. "Pokémon has given us a limited number of receipt codes, around 50 per location."
Scalping and Resale Issues
Initially, stores were given 50 codes, but they quickly ran through them. Even with the promotion limiting codes to one per person, some eBay listings surfaced with several codes available. This has continued for the new round of codes. A prominent response on X stated, "These codes right?" alongside images of online sales for the codes, with at least one having several codes on offer.
Mixed Experiences for Players
Some players were able to snag codes during the weekend from their local stores, while some had no such luck. "Waiting on 3rd chance now. Just called my GameStop. They’re out of codes (again)," one individual commented, before other players stepped up and provided them with spare codes for Shiny Koraidon and Shiny Miraidon.
Mystery Surrounding Distribution
Why the Shiny box legendaries weren't earned through a Tera Raid battle or given away online via the Mystery Gift feature remains unknown. For now, you must visit your nearest retailer and pray they have codes remaining if you desire a shiny version of these legendary Pokémon.
