I've run into the same problem as you guys with Borders. Either one or two weeks ago, I went to Borders to look for Shards and Shadows, but they didn't have it, so I went to the B&N which is so close you can almost see it from the Borders parking lot, and they had like 6 copies. But I also noticed that there did seem to be alot less stock in general in the Borders, there everything was really spread out with lots of open space, and then at B&N the store was packed pretty tightly. This is sucks for me because I tend to prefer to shop at Borders, I don't know why but for some reason it's always felt more casual to me.
Oh, and I went to both stores again this week, and couldn't find ASD in either store yet.
