I live in Brooklyn, so it would probably be cheating for me to do something like this. Living Local is very important to me and it's part of why I live where I do and happily pay the premium to do so. I go back and forth with how much of a commitment of time and money I'm willing to make, especially as I try to get my finances in order, but I do try to shop and buy local where I can.
