Pricing options

We have three levels of pricing. The regular registration price includes a new PC Manual and Trainer's Guide and is for all those who have never taken the training before. If you have previously taken the Trainer's Workshop/Course (since 2005) and would like to take it online as a refresher, you may do so for $200 and use your own material. If you pay $250 for the Refresher, you will receive a new Trainer's Guide.Explain how different pricing options might be valuable to different segments of your audience.
