if android do like this，i will spend all of my dinero.
Unfortunately "Life is Tough". Having said that we get these complaints quite often, however just as you are complaining about iOS promotions today, they also complain about Android promotions from time to time. There are even complaints across servers, but the reality is that each server and platform is a stand alone. This essentially means that the promotions are determined based on the data from those specific platforms/servers.
If you would like to make a suggestion as to a potential promotion, it would help if you would be specific about what you would like to see as opposed to posting screenshots of the bazaar boards.
