Pokémon GO Plus is back in stock at Walmart for the original asking price of $34.99. The Pokémon GO companion accessory can now be purchased via the retailer’s online store. It might be a good idea to act fast, however, as the device is expected to quickly sell out. Pokémon GO Plus recently went back in stock at Amazon as well. The device can be used with any compatible smartphone that has the Pokémon GO app installed. Once the device is paired via Bluetooth and a brief setup process is completed, players can encounter and catch Pokémon with the convenience of not having to look at their smartphone by simply pressing a button.
