This is what I don't get about alot of people who post on here... If you don't think that halving the price and moving more product can't gain more net profit... Then why would you have "buy one get one" sales on everything from mac & cheese to high end business suits. In real life, most businesses don't undercut each other by 1%, they generally do it on drastic levels like 25-50% to entice people to buy things that they might not generally buy. When you say people could just wait to sell their product for more to someone, you completely leave out the fact that they might be selling it to someone who would never buy it at your prices anyways.
