Academic text books cost a small fortune and a common bugbear of students. Many successful business ideas are borne out of everyday problems like this which is why Campus Book Rentals in the US has scored many brownie points with students and as a result cashed in. CBR rent out college text books, saving at least half the price of what the full price would be if purchased. Students have their own online account so they can keep up-to-date with the rentals and books are easily returned in prepaid envelopes. Other customer-friendly services include 30 day money back guarantee if the book is not the right one, rental extensions and buy options. Since establishment in 2007 the business has seen incredible sales growth and now employs 90 people. This business model has been adopted by savvy people in other countries, for example Acadreamia offers a similar service in the UK.
