Go to http://www.mikeshard.com/blog/contact/ and send a message to Mike's Hard Lemonade saying that you will not use their product until they stop supporting the Miami Seaquarium.

*Remeber it has more impact when they think that you were a customer before you found out about it.*

This is my sample message feel free to use it or alter it:

I used to be a customer of yours until I found out that you made one of your commercials at the Miami Seaquarium and used Lolita (the orca whale in it).  By doing that you supported the Seaquarium and it's horrible living conditions and abusive ways.  I am extremely disappointed in your company's action, and think that is was a bad business decision by your marketing team. Now that people who support Lolita's retirement plan and The Orca Network (also based in Washington State) know about this I KNOW it will severely continue to decrease your profits.  Please consider becoming a supporter of the Free Lolita movement and visit orcanetwork.org for more information.  Thank you for considering this and I hope you'll do the right thing.
