I would not send them money for a fax blast. I don't know how legit this organization is, but I never send money for fax blasts.
Just use the information and decide what you feel you need to do. For me, I plan on making phone calls.
If you plan to make calls, keep in mind that representatives won't usually talk to you so it's likely that you will only be able to leave a message, but that's good enough for now.
Please take a look at the chart they show and then help me spread the word.
