How can you charge more for a commodity? Here’s one of my favorite examples.
24 ounces of ketchup at $0.07/oz.
Turn that idea on its head.
32 ounces at $0.079/oz. The price per unit goes up almost 13%. Not bad for a commodity.
Note that the different sizes make it harder for buyers to know exactly how much more they are paying. But hey, who doesn’t like upside down ketchup bottles. You can probably even make the case that you end up wasting less ketchup.
