The info in that thread is great, but I've also found that the rep for their charitable giving has changed quite a few times recently, and varied by region. If you write to info@ricolausa.com, they should be able to point you in the right direction. They like to hear that you're a theatre company (not for profit, if applicable), etc. I usually include how much our actors appreciate it. It helps if you include the shipping address of the theatre on the initial inquiry, so that you save a step of back and forth (the speed of the back and forth has varied wildly). Once you finally get the confirmation that they'll send you some, it comes pretty quickly.
