Yes, though there is a limited window of time. You have 7 days from the date of purchase to buy your rental book. The buyout cost is typically based on the retail price of the new or used condition (depending on which you rented), plus any applicable taxes, per state and local laws.
If you’d like to own a rental, or “buyout” a book, just log in to your account and go to the Buyout section of your rental history. Select “Buyout,” then add it to your cart and check out using a valid credit or debit card.
