Customers able to download more than one freebie

On my website https://www.hookedondigiscrap.com I offer freebies and I thought I had it set to where one customer can only download one freebie but once they check out - they come back and place more orders ... I know they are freebies and it should not matter how often they download, but I would still like for people to only be able to download one here are my settings which I thought were putting the limits on but I guess not:
Product Qty Minimum: 1
Product Qty Maximum: 1 0 = Unlimited, 1 = No Qty Boxes
Product Qty Units: 1
Product Qty Min/Unit Mix: yes checked.

Is there a way to limit one per customer only even when they come back to tell them you already downloaded this please buy something else.
Thanks so much!!!!

This is not a built-in feature of Zen Cart at the present time.

If you wanted to use a coupon in order for them to get a certain item free, and restrict that coupon to 1-use-per-customer, that's the closest you can do at the moment.

Thank you very much for that answer :) not a problem at all I just wanted to make sure Thanks again!!!!
