BKS packed with People and a BKS with people buying books is two different animals. If BKS can't see at least a revenue increase on the heels of Borders BK then it's in deep chit.
Same story that we saw with Circuit City and Best Buy, a loss of a competitor amazingly did not help and is actually just a precursor of a dying business model. If people are buying their electronics online, I guarantee you they won't hesitate to buy books online as well...
