I'd tell you who the guy is that is setting all the prices...but he's watching us. He listens to everything we are saying through his giant microphone that is attached to the Hubble telescope...shhhhhhhhh...the truth is out there.

p.s. yes I have seen prices change on goods already in stock, every week Best Buy and other stores have sales where some items get marked down while items from the previous week's sales get marked back up. This is the advantage of using bar codes and labeling prices on shelves instead of on the individual item.
