B) I want to post my book, but I am not ready to sell it yet. Can I still post it?
Absolutely! The sooner you post your book, the better chance you have of selling it. Ideally, you could find a buyer for your textbooks before the semester even ends! When posting a book, there is a field called, "Date Available for Sale." This way, you can inform the buyer of when you will be done using the textbook, but can still post your books today!
