I once got some pj's for my daughter at Old Navy for $5 each. The regular price was $14.50 but they were hanging on a rack that was clearly marked 2/$10. There were lots of them on the hook so I knew that they were put there by an employee, not a customer. Well, they rang up as $14.50, I tell the cashier that the sign clearly says 2/$10, he says that's not possible but I'll go check. When he came back he apologized, said that the sign was put on the wrong hook and gave them to me for $10.
Did you get my answer out of all of that. Get them for $39.
