The video tutorial guides viewers through implementing a grocery store system using classes and list buffers. It covers setting up the project, defining functions to print item details and calculate totals, iterating over objects, and handling user input. The tutorial emphasizes using list buffers to store class objects and retrieve information, culminating in a demonstration of the system's functionality.

What is the significance of the 'total' function in the context of the grocery store system?
