About knetbooks

https://www.knetbooks.com

The founder of knetbooks believes that renting textbooks can save college students a lot of money. Due to the low price and direct leasing process, knetbooks quickly became the main source of cheap textbook leasing. The success of the bookstore was so obvious that a major textbook retailer bought the company. Under the new management, the number of books that can be rented has increased, transportation time has been improved, and a dedicated customer support team has been added. University tuition is expensive, helping college students save money is the core of the store business model. Since 2009, the company has been keeping its promise to allow students to rent textbooks and help them save hundreds of dollars per semester.
