Yesterday I asked CP if it was possible to get iBlitz in the United Kingdom. Here is their reply!
Club Penguin teamed up with GeoPalz to offer this for players in the U.S. With that said, you can get a parent or guardian and check our products page or help you find them in your area!
iBlitz is available in the UK but it will not add coins to your account. Therefore, Club Penguin fans, don’t waste £30 if you just want it to add coins to your account. You get cool items though!
