Tito's Vodka sends out Christmas gifts every year to their Tito's Tasters members. Members also receive emails with recipes, news, and event updates. You can sign up at https://www.titosvodka.com/titos-taster and enter your info. Once you sign up, you will receive a welcome email. At the bottom of the email look for “Manage your profile”. Click on the link and login using your email you signed up with. Then you can add your physical address.
The Christmas gift is not advertised but comes every year. Apparently some are reporting that they are receiving reminder emails to make sure their address is updated by October 11th so try and get this done now if you want this year's gift.
