You mean it's a steal when Apple adds this to every unsuspecting customer when they come into the store to purchase something?
Apple has continued to remove features and components from their product boxes over the last several years. I get the shipping efficiency and environmental argument... but then they come in and charge $59 for charger technology that other, reputable brands can deliver at half the price with the same functionality.
The color-matching braided cable is another $49, for what it's worth. So to get lower wattage charging (compared to the last-gen wall brick MagSafe charger @ 60W), for a new set of charging capabilities you're looking at $108 - 36% MORE.
