I went to my local walmart here in Maine yesterday and they had the sales flyers there for BF. My laptop said $398 on the flyer. The manager was in the middle of "stuffing" all the sales flyers with black and white photocopied pieces of paper. The laptop price on the photo copy was $378, other prices were lower to.
When asked he said that the flyers were printed about 6 weeks ago, and since some of their comptetition came in with lower prices, they had to lower their prices to compete.
You always seem to get a different answer depending on who you talk to....but I don't really care what the reason...at least they are lower prices now :)
