"Tower of boxes"

This was a picture I took on Friday night at a local No Frills I was shopping at with my aunt.
 The title: "Tower of boxes" came to me when I was taking this picture.
 I took the picture when we were finding a lineup to checkout. I saw it and I thought "Oh, this is just too good." I said to my Aunt, "Find a lineup, I'll be back in a minute, I just gotta take a picture of this."
  And that's the story of the "Tower of boxes".
