please answer my poll question

We’re rethinking the really loose way I do my green smoothies classes. Please weigh in here. Would you rather attend my class:

1. Free


2. Paying $15 with a chance at a free $400 BlendTec Total Blender? (and maybe the host of the class might throw in other items or gift certificates for the drawing), preregistering online.

Preregistering online will help me get a headcount to plan.

Thanks for your response–don’t look at what anyone else says before you answer though!
