Hardly seems a "deal". If you intend asking for your money back prior to placing your order why would you order the product in the first place?. Seems a case of "caveat venditor".
I didn't intend to ask for my money back when I placed my order....I just felt the bulk of the ebook was mostly "fluff" (up to at least page 83). It included of the 112 pages:
1. Cover sheet and table of contents (pages 1 to 3)
2. History of sudoku and general info on the puzzles (4 to 15)
3. Basic solving techniques (16 to 44)
4. More basic solving techniques with lots of 4x4 puzzles (45 to 64)
5. More basic solving techniques with lots of 9x9 puzzles (65 to 77)
6. Intermediate solving techniques with 9x9 puzzles (78 to 83)
7. Advanced solving techniques with 9x9 puzzles (84 to 98)
8. Misc stuff (99 to 110)
9. Website resources (111 to 112)
Is it worth $17??? If you are an intermediate to expert solver, no....if you are a beginner, then probably. It does have a LOT of information.
