marketing energy drinks/water bottles

[spookhaven]

Anyone use any of this stuff as marketing tools at fairs, carnivals, your haunt, stores, etc? How did you track the effectiveness? Example: Do you put a coupon on it if they bring it back to get money off a ticket?

Looking for new marketing tools to use this season and got one from screamingzombieenergy.com at the HHA meeting.

Feedback would be great.
