Aisle for all seasons

There’s an aisle at the grocery store that changes with the seasons.
In the months before Halloween, it’s stocked from top to bottom with candy and decorations.
Then, a few days before Halloween, the last dregs of candy and the ugliest decorations nobody wants are put on clearance on one shelf, and the Christmas stuff is stocked.
A few days before Christmas, it’s down to the dregs of decorations, and the Valentines candy and stuffed bears are stocked.
Then it’s St. Patrick’s Day, Mother’s Day, Father’s Day, Fourth of July, and back to school supplies.
Until it’s time for Halloween.
