Going back to school just got a little easier for some college students.

Amazon launched the free Amazon Student app for iPhone and iPod Touch users on Monday. The app will allow students to scan barcodes on textbooks, electronics, bedding and more and check for better deals on the Web site. 

The app will also allow students to trade in textbooks, electronics, video games, DVDs, and other items for Amazon Web site gift cards at the end of the semester.

"Students care about getting the best deal possible on their textbooks and all of their dorm essentials, and now they can easily compare prices and save money no matter where they are," Amazon's vice president of books Julie Todaro said in a company press release. "Plus, for eligible textbooks, when they're done with the book, they can scan the barcode, see the trade-in price, and submit the books for trade-in with Amazon, all right from their phone."

Nearly one million textbooks are eligible for buyback, according to the press release, and students can get up to 70 percent back.
