There is a forum on the weightwatchers site, which has loads of useful information on it. If you don't want to do the meetings, you may be able to signup for online, or simply do it yourself with the help of the forums. Many people do. You would just need someone to help calculate how many points worth or food you get to eat each day, and possible pick up a calculator or points guides that list the points of different foods (I am sure if you google you will find alot of this info the web).

As for prices, you have two options for meetings:
1) $59.95 a month - Weight Watchers unlimited. This covers the meetings and all of their online tools. It is also the cheapest method. It is direct debited off a credit card (matercard / visa) every month. Can be canncelled at any time, no obligation, no contract.
2) $19.90 a week - this just covers the meeting not the online tools, plus there is an extra $33 registration fee with this.

Anyway, I don't want to push this, just to give you the info. so if you want any more information feel free to pm me. I am a leader with weightwatchers, so am qualified to answer any questions you may have about the program.

good luck whatever method you choose.
