Problem

The retention team is building a loyalty tier for customers who show broad purchasing behavior rather than repeat-buying a single item. For each user, show their username, how many different products they have purchased, and what they have spent in total across all transactions. Only include users who have bought from at least two different products. Present from the highest total spend to the lowest.

Summary

They shop the whole catalog.
