You can afford a 700 smartphone and can't afford a 19 additional charger ?You never lost anything in your life? Chargers are objects. Just like anything else. Many people have more than one charger. One at work, one at home, one in the car, one in a suitcase...etc etc. Most people whose work requires frequent traveling need more than one charger. And easily lose chargers. If no one needed extra chargers, Apple wouldn't be selling them.
I still stand firm by my point. Cutting the chargers price in half, will solve this problem a great deal.
