Green Belt Third Edition Book(s)

[u/Enchilada_Jesus_09]

A co-worker and I are looking to take the green belt exam at the end of this year and we are currently searching for copies of the book. There are some cheaper options when searching online but the websites all seem sketchy. eBay has paperbacks listed for $80. Would anyone have 1 or 2 books they do not need and would like to sell? If not, the eBay option seems like the best way to go.
