The mini cart contains your order-level information - it summarizes the totals across all cart contents, and details order-level things like the donation amount.

The Big Cart is where you'll find complete line-item detail, which includes the seating assignment, Price Level, original price, discount amount, item fee total, sales tax, and total for each item in the order.

You can also see the total quantity and the final price subtotal (including discounts, item fees, and tax) for all tickets to a given Event Instance. If there were discounts applied, you'll also see the pre-discount total in crossed-out red text.

You can now see all the shows contained in a subscription package, even if you haven't fulfilled it yet! Placeholders will show with text noting they're "Unfulfilled" here:

Fulfillment is when you assign seats (or GA tickets) to the package. As you do so, those details will replace the "Unfulfilled" text, and once all placeholders are fulfilled with real tickets, the status of the entire package will change to "Fulfilled" as well.
