I see that alot of people offer this for their parties. What do you give? I see some people offer free cookbooks if you bring 2 friends. Do you just add stuff like this to the order? That would mean we'd pay full price for it, right? My recent party this past weekend had a bad turnout (this could have been b/c they wanted it at 2:00 on a Saturday) so I want a way to offer my hosts an increase in attendence. What does everyone else do? Thanks!
