Koshka brings up some very good points.
If money is your issue, you can always join and pay for one meeting (they often have free registration promotions going on, but I'm not sure if one is going on now), get all the materials you need, stay for the meeting to learn from the leader how the plan works, and then have everything you need.
That is probably the cheapest way to get what you need in as far as materials is concerned.
