Here's a quick explanation:
It's not a coupon because the sponsor (Jarritos) wanted to send an actual product to let winners try/enjoy the soda right away—especially for limited-edition or featured flavors. This helps build brand love and excitement more tangibly than a discount code might. As for the huge box: Shipping regulations for beverages (glass bottles, liquids, etc.) require sturdy, protective packaging to prevent breakage during transit. A single bottle needs padding, a strong outer box, and sometimes extra space for compliance and safe handling by carriers like UPS. It can look excessive for just one item, but it's the standard way to ensure it arrives intact and chilled/fresh if possible.
