I'm new to the game and I've been enjoying it quite a bit so I decided I would purchase the campaigns. I was browsing your specials and I found the All Campaigns Bundle which offered the "First Four" for 18 plat. I purchased 30 plat and attempted to buy the All Campaigns bundle, not enough platinum....because when you are browsing the store it's priced as 32plat. How do I get the price advertised in the special?
