Decided to call B&N to see if they could separate my order and it turns out my order had already been reviewed and would be shipped out today! WOOHOO!
Lesson learned- Read all of the terms and conditions...not just enough to answer the only question I had.
Update on this....just got an email from B&N that they need my approval for a 30 day order extension. Apparently the girl I talked to that said my order was to be shipped out that day was completely lying to me. I'm not approving it. I wanted those books last week. Guess I'm going to Amazon to get them now.
