Another way of paying for those things is by not having a $100 unnecessary smart phone plan.
I'm sure I'll get ripped for this as it gets brought up on these phone forums too much, but:
I swear, the thing I'm amazed by most as a new DC resident is the middle and high school tourist groups. The number of kids who don't have jobs yet still have iPhones and Blackberries simply boggles my mind. They call MY generation (I'm 23) generation ME but I can tell you that I don't know many people who had smart phones before college. I felt lucky when I got a camera phone....
Times are changing. Almost everyone uses a smartphone in high school and a majority of them are iPhones. How do I know? I'm an incoming senior in high school.
