Went in about 3pm. The good news is Clif Bars are in fact $0.99 :) But the place was mobbed! I mean, there's no way I was going to wait on that line. They actually have a mobile employee who holds a tall sign that reads "Line Begins Here." It was literally half-way around the store. Just navigating the isles was an exercise in extreme patience.
Maybe it's just the initial hype, but with crowds like that I won't be back anytime soon...unless I happen to be walking by right when they open in the morning or something.
