Any rental that is not returned by the due date, will be extended for 7 days at 10% of the original rental price. If it is still not returned after the 7 day extension, it will be considered intent to purchase and your card will be charged the non-return fee. Our non-return fees are very low in comparison to most other rental companies. We only charge you the replacement cost of the book, which is 50% of the new price, instead of the full retail price, which is 75% of the new price. Keep in mind that the non-return fee is in addition to what you already paid to rent the book since the rental period you paid for is already over and that fee has already been expensed. (Example, if a book sells for $100 new and $70 used and we rent you a used copy for $39, the non-return fee would be $50).
