If you play Pokemon Go you may have missed the pop-up news item in-game this weekend there is a one-off deal in the shop. Once only you can get a storage space increase for pokemon of 100 for 200 pokecoins as a special bundle item in the shop. You can buy coins or get them through the gym system in game with no real money cost.
Personally, I don't think Pokemon Go in-game items should be in the deals section unless it is a special code but if 30 ultra balls are then so should this. Yeah, the game is still a thing before the inevitable response.
