I'm not sure when they've done it in the past...may depend on the amount of merchandise they have left. Both of our Target stores were almost bare by the morning of Dec 27th. I was shocked to see that they had NO lights or outdoor decorations, wrapping paper, tissue paper, or boxes, and only had very few packages of ribbons/bows left. They had mostly ornaments left. Very slim pickings compared to previous years...I can't even imagine what would be left when/if they go to 90% off.
