I am trying to show the prices of different non-consumable IAPs on the app. When I display the the price it is not the same as the price that is shown on the confirm popup (the popup that the user gets when they try to purchase). Sometimes it's a few € off. The right price only shows up for some locales. I am also using localized price to show the user the price in their currency depending on their price locale, maybe that is affecting this? Any help would greatly be appreciated!

Hi, I have implemented an promotional offer of 3 free months which is promoted when a user tries to cancel their subscription. Currently the offer, when selected is applied for 3 months from date of purchase. However, I want it apply 3 free months after their current subscription period. Is this possible?
