I often go through 10-15 pages of Google searches, because there can be some awesome items further back in the search. Just because it doesn't get a lot of hits doesn't mean it isn't valuable.
I've also discovered a large number of books that can be picked up for free on various sites and a shocking number come with resale rights. I bought one e-book that I wanted and got 15-20 other e-books with resale rights. I think that I only paid about $20 for all of it

One day I'll get time to search the titles (which I saved of course) and see what I can do with them
