I've literally been asked for exact details of programs and diets outlined in 20 to 40 buck e-books.
Working ONE day tending bar, waiting tables, folding clothes, or shoveling snow can get someone the damn book!
Actually, even if someone worked at some down-and-out bar just pouring beers, they could afford five to ten e-books from working one weekend (maybe more).
Even if one succumbed to begging and borrowing, they could acquire 20 bucks from asking their girlfriend, friends, and family members for one to five bucks apiece (which they probably wouldn't ask you to pay back).
How do these people afford gym memberships if they can't afford a 20 buck e-book.
