I have a huge library and I can’t resist the temptation of buying new ones. Now my library is running out of space so I have decided to get rid of the books I didn’t want.
There is one website, where users can actually sell their books just by entering ISBN numbers and if the books are sold they will be shipped for free too. The site is called Cash4Books and I will test it now, hopefully everything works fine for me. I will leave you a note about my success.
