As Philjolet posted, not uncommon at all. I've seen homes with 112 at the outlet and others at 129.
My home is 121.7, so pretty close to what it should be. I would not worry, the real problems come with very low and very high voltage.
Two years ago we had a transformer fail in the alley and we were getting about 68 volts for almost a day, until I figured out what was going on and called TXU Electric.
We lost our clothes dryer, microwave and later the refrigerator due to "brown out."
