STUPID OR MISLEADING FOOD PRICING?

My wife had a doctor's appointment today and after we stopped at a supermarket to do some shopping. We bought some mini-apple pie. The price caught my eye as being kind of odd. The price made me laugh as a matter of fact, 10/$10! WOW what a bargain! What about if I only wanted to buy one? How many people do you think feel obligated to buying 10? Obviously we did not buy ten, we bought what we wanted which ended up being 6.
