We will fire our copywriters if you still need the answer :) But OK, once again the rules are:
1) buy KHOR online with a link you got after entering your email and zip (if you lost the link, send a request to email@example.com
2) send a receipt to firstname.lastname@example.org
or to Instagram direct @khor_usa;
3) create Instagram reel with your cocktail recipe and tag @khor_usa as a collaborator of your reel (see the screenshots in step #2 how to do it correctly).
