11. Do they have solid, money-back guarantees for a substantial period? (Or do they play the 30-day game, with return reauthorizations, restocking fees, and other hoops you need to jump through?)

It's called "putting your money where your mouth is". Because I know what my information has done for me and for scores of my students--all across the country--I have no problem giving a rock-solid, no-nonsense guarantee. I laugh at the guys who play all these games with return authorizations, and guarantees contingent on proving you applied three techniques from their book, etc. Do they believe in their own stuff, or don't they. Well, I believe in mine, and I back that up by taking the risk off your shoulders, and placing it squarely on mine.
