Before we hit the Saturday farmers’ market yesterday, we stopped by the book sale that’s put on by the Chico Friends of the Library. (It’s every Saturday, except for holidays, from 9:30 to 11:30 a.m. at the library at 1108 Sherman Ave.) We go almost every week, and we always score great books and magazines way cheap. This week we loaded up with dinosaur books, recent National Geographic Kids magazines, craft books and more for less than $4. It’s like a treasure hunt and money saver all in one.
