usps.com 1 Ginger @2013-05-01 The company at the top of Google is not the USPS. They call themselves the USPS change of address assistant. They are a scam... run. I thought I was changing my address w/ the USPS for $1.00 and was charged $29.95 by this scam company. Make sure you are changing your address w/ the USPS, not any other company.
