Some beginner questions

I’m pretty new to this money, I’d love if you could help me with some questions:
1. Is it possible to prepare pre-made shopping packages?
For example, will there be three packages to purchase: a package of 100 credits, a package of fifty credits, and a package of 20 credits?
2. Is it possible that the date of expiry of the points will be by the time of purchase automatically, and it will end for everyone according to their purchase time, and not according to a predefined time for everyone?
3. How do I set up a weekly recurring subscription every month?
4. Is it possible to have two types of points, and can only be purchased in the store with one type of point and not the other type?
