Stop drinking the Jonestown kool-aid that's been going around my friend. Your time isn't so valuable that you can't spend 15-20 minutes doing a diligent search online.
The ebooks I mentioned in the previous post were college textbook stuff. As basic as the stuff gets. You would need to be already under the influence of the kool-aid getting passed around here to think that's an honest price. It's not.
My point is this: the people trying to sell you stuff here are not your friend.
