Oskar went into the grocery store in June (2011) and saw a shelf piled high with boxes of candy canes that are on sale. Oskar thinks that this is strange and assumes that they are left over from last winter. He grabs one of the boxes and examines it for a sell by date. The date on the box is 11/2011.
