For more than a month now, can not schedule packages pickup via the USPS.COM website. Keep showing error as "address is not valid." I have been using this service for more than 10 years, and one day, it just won't let me do it any more. My address didn't change, the type of packages are the same as the ones I usually ship. I have to make a pick up via telephone every morning to schedule pickups. Extremely frustrating and annoying. Call the local post office numerous times and have gotten no answers. Great service, and now they are cutting Saturday delivery, nice going!!!
