There are many different websites to sell textbooks, one being Half.com, a division of eBay. In order to sell books on Half.com, a personal account must be created. The book will need to be in good condition: no tears, rips, missing pages. The ISBN and UPC code is required to list the book on Half.com. These codes are usually found on the back of textbooks. Be sure to find out a shipping price, and give options to the buyer. Check to see if other similar textbooks are for sale on Half.com to get an idea of a listing price. If there aren't any matches, go well below the original paid price. The condition of the book is something to consider when pricing. The book will sell for less if it is withered or overused. The listing should be posted on Half.com within a few hours after all steps are completed, and the sale begins.
A personal account is also needed to sell textbooks on Facebook.
Facebook has over 200 groups a member can join to sell textbooks. Many students from universities all over the world are members of one of these groups. Look for a group from a university or state that iis closest to you. Many members post the exact title of books they are looking to buy, and others list what they are selling.
Many bookstores, such as Borders, Barnes & Noble and Hastings, buy textbooks. Check locally first. Also, most university bookstores buy used textbooks. As a convenience, these stores also let you sell books online.
