I will confess, I'm a novice when it comes to European travel, much less Italian travel.

I have heard from people personally, in YT videos, and blogs, that it is possible to find discounts when it comes to rail travel, I just have a few questions:

1. I'm trying to get from Malpesa Airport to the Milan Cadorna Railway Station. Some websites I've tried seem to not recognize it as a "location." How can I find a ticket ahead of time for this station? Does it have a website or place I could visit?

2. Let's say I get a ticket online from a site like TrenItalia or Omio. Do they have apps, or how can I retrieve my ticket once I enter the country?

3. What are some good websites/apps to look for deals? I know it's a basic question but I'd prefer to ask rather than be too prideful and accidentally give my credit card info to a scam website.

Thank you for reading and any feedback is appreciated.
