I saw that in the Play Store in the app description: https://play.google.com/store/apps/details?...e=search_result
it says ”Introductory offer: 30% OFF regular price for a limited time.”, but when I try to upgrade there is a price of 7,45 euros (6,26 + Taxes) and it doesn't say anything specific about the discount.
So what is the normal price? Or is the discount no longer in effect?
