After my cat chewed my cord (the second time in two months), I needed another replacement (the second time in two months). Fortunately for me, Experimac is not only close by but they carry the portion of the cord that needed to be replaced. This is at a nice price vs. the Apple store cost of an entirely new plug. The staff member quickly found the part I needed, rang me up, I paid, and was out of the store in about 5 minutes. Not bad when for a busy person like myself!
