Rainbow Books Used Book Buying Policy


We give trade credit and cash. We will make you an offer based on the books you bring in. Your trade credit can be used on anything in the store and never expires. For cash buys, we will need a valid Driver’s License or other state issued photo ID.


 While we do have these basic guidelines, what we take is based on the discretion of the book buyer taking care of you. We have the right to refuse any books we decide we cannot take.  

We do not have a cash book buyer available on Sundays and Mondays. 

What We Buy


  • We look for books across subjects in good condition. What we take depends on condition, space available, and our current inventory. 
  • We tend to take paperbacks over hardcovers, with exceptions in children’s picture books, teen books, cookbooks, and history.

What We Do Not Buy


  • Books in poor condition:
    • Water damage
    • Torn covers/dust jackets
    • Hardcovers without dust jackets
    • Books with broken spines
    • Books with stains/highlighting/writing
    • Books with odor or mildew
  • Ex-library books
  • Advanced Reader Copies
  • Reader’s Digest Condensed
  • Encyclopedias
  • Textbooks
  • Partial Sets of Books

Our Process


First, we sort your books into what we will and will not take. Then we offer a value of trade credit or cash. The books we do not take can be donated to the Boise Public Library, and we do have Gift Book Doner Receipts available. 

If you have more than 25 books, please call to make an appointment. 

If you don’t want to donate the books we cannot take, you must be able to wait while we go through your books. If this doesn’t work with your schedule, we can make an appointment at a later time/date.
