I've already subscribed to Aeronautical Database and I'm interested in one of your country packages, could you explain how your pricing works for this?
Yes, we can definitely give you a breakdown of how it works. We'll give you two example scenarios that most likely happen. (Note: The scenarios are just examples and are not based on real data.)
Scenario 1 - The user has more than 3 months left in his first product subscription (example product: Aeronautical Database), and the user decides to purchase a country package (example package: France), since the user still has more than 3 months left on his first subscription (Aeronautical Database), then the expiration date of the user's country package will be carried over to the first subscription and will have the same expiration date as the user's first subscription.
Pilot has subscribed to Aeronautical Database last March, currently he has 6 months left for his Aeronautical Database subscription and he decided that he wants to subscribe to the Standard France Package.
99.99/12 = France Package is 8.33 per month; Pilot has 6 months remaining; 8.33 * 6 = 49.99
19.99/12 = Aeronautical Database is 1.665 per month since Pilot has already paid for his subscription, so we minus the 6 months that he's paid for his Aeronautical Database subscription 1.665 * 6 = 9.99
(6/12) * 99.99 - (6/12) *19.99 = 40.00
0.5 * 99.99 - (0.5 * 19.99) = 40.00 (Simplified)
49.99 - 9.99 = 40.00€ (Simplified)
Scenario 2: The user has less than 3 months remaining to his first purchased subscription (example subscription: Aeronautical Database), and the user decided that he wants to purchase a country package, then remaining months left of his first subscription (Aeronautical Database) will be added on top of the whole year of the user's new package expiration date.
Pilot has subscribed to Aeronautical Database and has 1 month left in his subscription and he decided that he wants to subscribe to the France Standard Package.
(1/12) + 99.99 - 1.665 = 106.66€
8.33 (remaining 1 month) + 99.99 - 1.665 (Aeronautical database) = 106.655€
