With the holiday a few days away, many places are selling trees as best they can.  But this one is giving you half off each tree.  The question is which half are they cutting off?  The top or the bottom?  It does not say that the trees are half price.  It says that they are half off.  So where do they cut them?  Maybe they have a way of cutting it in half vertically.  Maybe one could mount it up against a wall.  I wonder if they sell mounting clips for that.  It certainly would save on decorations.
