Shipping Boxes

We were at the DI tonight, to get out of the house for a bit.  We saw all these boxes and wondered "what's in them all?"  the answer?  Nothing!!  just a bunch of empty boxes with Styrofoam in them to ship parishables.  this, to me, seemed absolutely ridiculous.  there were TONS of them!  There were even more than this out in the back yard area.  it also makes me wonder where did they all come from?
