How to capture all purchases of a specific product

I need a report that will show the customers that hav purchased a membership (specific product) that updates going forward so that I always can pull a complete, current membership list. So far, I can’t find or create that report with accuracy. Any ideas or magic potions?

Thanks in advance for your help and wisdom.

Are you tagging people as they become members? If so then you can edit the search criteria to show contacts with that tag and then save it as a saved search. Pull that up from the drop down to the upper right any time you need it moving forward.
