Is Gameshop Legit. Simply they have conered big. But, if there is nothing else suspicious on the cartridge, shiny legends with 6ivs etc, you should be good.
They operate more than 6,457 retail stores through the usa, canada, australia, new zealand and europe. The website is clean, and there are some interesting prices, but not enough for me to be willing to lose my money if it's a scam. They had great energy, were friendly and knowledgeable about their products.
