We had set up a Drupal website with Ubercart that sold tickets to events and the client needed a convenient way of displaying a list of customers who bought tickets to create a check in list. The Who Bought What module fit the bill perfectly. This module comes preconfigured with:
- Selectable list of products to display customers
- Sortable columns
- Export to CSV
You could replicate the same functions with Views and make it more extensible, but for simpler store configurations this is self contained and ready to go.
