Pokémon GO players can now increase the max number of items they can carry. By purchasing Bag Upgrades in the in-game shop, your Bag could carry a total of 1,000 to 1,500 virtual items. Players can now buy six Max Revives for 180 PokéCoins or 10 Max Potions for 200 PokéCoins. These particular items are even available before unlocking them. Pokémon GO players can spend real money on PokéCoins, the in-game currency of Pokémon GO. PokéCoins can then be exchanged for power-ups, extra items, and other enhancements.
