Please note that the shop discounts system hasn't been applied yet to the Mobile Version. Items which should be on sale on the desktop version do not have the same effect on the Mobile version, so, the price will stay the same (original price). Do keep updated by following the news to know when this changes. Also, GooglePlay is the only payment method for the mobile version. Items can't be purchased otherwise.
