When I shop sales for kids' clothes, I only look at the size and the price and not the style.  On super jumbled clearance racks, it takes too much mental energy to size up each and every item while also trying to bargain hunt.  After I have a stack and take a few minutes to review them, it is pretty obvious which items I don't want to take home.  And when I rehang them, my batch is size sorted for the next shopper.
