Hey Claudio,
Here are the answer to your questions:
1. You can purchase "Extend support to 12 months" which will give you a very similar price (see the attached screenshot).
2. There will no longer be a "Loyalty" discount (to renew your subscription before it has expired). However, for some special events we will still announce discounts on Themeforest, but it will be in very rare situations.
Today it one of those situations! Today InspireTheme turns ten and later on today we will announce a discount promo offer for our birthday
3. Yes, exactly. You simply purchase any of our templates on ThemeForest, contact us for verification, and then you regain access to download all templates from InspireTheme.com.
Yes, you can purchase a template before your subscription has expired and this will simply extend your subscription with 6/12 months.
