Just to add to this list.....there is also 1 used bookshop in al-madinah called Maktabah al-A'ayaan. It can be found just off sultana street behind the old Bin Dawood supermarket. The benefits of used bookshops are that you can find books for very cheap prices and they tend to be in good condition.
