Coca-Cola offers a free Cinemark Movie Club 1-Month Membership when you enter a Coca-Cola product code online or scan a Sip & Scan icon using a mobile device. That's a savings of $9 for a 1-month membership, which also comes with a free regular adult movie ticket, 20% off concessions discount, and other perks. Deal ends September 24.

Note: This offer is valid for new Cinemark Movie Club members only. The membership will automatically renew each month at $8.99 per month unless you cancel.
