I've recently discoved the Ambassador's Program with Maker's Mark. Happily, it's absolutely free and requires only the completion of a simple form. The main "duty" of would-be ambassadors is to simply promote the Maker's Mark product. And I mean "promote" in the loosest sense of the word: tell a friend about Maker's and you've accomplished your obligations.
Some of the perks of being an ambassador include getting your name etched into a bona fide Maker's Mark bourbon barrel, and the opportunity to buy a bottle from that batch. In addition, you get access to a members-only website, and advanced notice of certain Maker's special releases. The exclusive website is pretty cool.
Becoming an ambassador is worthwhile. It's free and you get to tell people your own personal bourbon barrel is aging in Loretto. I'll keep you posted with any other yet to be discovered perks of ambassadorship. Anyone who is a veteran ambassador is encouraged to share their experiences.
