This book provides practical know-how for monetizing a blog, explained in 73 points. I purchased it new and read it once, then stored it at home. There are no major scratches or writing, but there are some areas that are slightly creased. Please check the photos. It's in relatively good condition, but as it's a used item, please refrain from purchasing if you are sensitive to such things. - Title: How I Earned 500 Million Yen with a Blog - Author: KIGUCHI - Price: 1600 yen - ISBN: 978-4-478-15879-3 - Contents: 73 points of know-how for blog monetization Thank you for looking.
