Pokémon GO periodically provides promotional coupons via collaborations and unique events. Offer coupons may be redeemed for Poké Balls, Lure Modules, Lucky Eggs, and other products.
Trainers may often utilize Pokemon Go promo codes to get important in-game stuff. Poke Balls, Incense, Berries, and other random goods might be awarded as rewards. Promo codes are only valid for a limited time after they are released, so you must move fast to take advantage of them.
Aside from utilizing codes to get free things, you may always go to Poke Stops and Gyms anytime you can. Doing this every day helps you to collect the greatest number of goods. However, there is a limit to how many stuff you can carry, so you may need to get a backpack!
