I registered for courses for the summer, but I found I can't get my textbooks in time (I live abroad). On Amazon, the books are about $10 each. All of the US-based sellers don't ship here and the local merchants charge 10 times this price. So, I withdrew all of my courses, and changed to the fall term, thinking that would give me some months time to get something sent here. Now, I find all of the professors have changed their books, now $200 per book. I tried to order regardless and find the books aren't even published yet!
