Thing is, people will stupidly think it’s a better deal. A store near where I work normally has jewelry marked down considerably – for instance, one of their sections is normally 60% off ticket price. They ran a half-off sale… And ran out of a lot of stock in that section. When one customer asked for a rain check on a necklace, the employee told her if she waited until it was back in stock, she could get it 60% off, a better price. Customer acted offended, demanded the half-off instead since she ‘knew better’.
