I don't prefer second hand books because they are dirty and contains lots of germs. Most of the pages are not proper, it is either torn or hapazedly arranged. I prefer new brand books.
Its your choice if you prefer BRAND NEW BOOKS. But you seems to have lot of misconception about second hand books. No doubt, you might have come across few of the torn books being sold , but it might surprise you to know that most of the books sold are in good conditions. But what I find very amusing is your misconception regarding the presence of germs. :) Like second hand books, New books are also being handled by many people- salesmen, customers who come and browse the books etc. So, they might also be having germs. So how do you manage that?? :)
