When you open this page we ask eCampus, Amazon, Knetbooks, BiggerBooks, VitalSource and RedShelf for their current prices on ISBN 9780262162098 and sort every offer by its total with shipping. Rental rows show the term (semester, quarter or short term) and that term goes with you to the store's cart, and eBook rows link straight to the 180-day or no-expiry option you picked. Prices are rechecked at least every 30 minutes, so confirm the total at checkout.
