Bkstr.com is an alternative address for efollett.com, a website that provides easy access to the online bookstores of many colleges across the United States and Canada and many K-12 schools in the United States. To find an online bookstore, you must first indicate whether the school is a college in the U.S., a college in Canada, or a K-12 school in the U.S., then select the correct state. Then, you can pick the actual institution from a drop-down menu. When you select “submit,” the site takes you to the school’s online bookstore directly. You can also check out the “Cash for Books” tab, which provides information on how to sell your books back either to your school’s bookstore or to efollett.com itself. If you want to sell back to your school, you simply select the state and then the school, as with finding the bookstore, and the submit button will take you to your school’s bookstore’s sell-back page. Otherwise, select the Sell Your Books Online link and put in the book’s ISBN number. Based on various factors, efollett.com will buy your books back at the current normal market price. The site is a part of the Follett Higher Education Group, which claims to be the largest educational bookseller in the U.S.
