This location is horrible. The two ladies at the counter said that couldn't help me set up a post office box. After hiding in the back for 10 minutes they came out and finally asked how they could help me. I told them I just need a po box set up. Nothing fancy. After explaining how id been waiting for 15 minutes with no other customers in the room I was denied service. They finally got another lady out of the back to do it. This po box was mainly for a very important peice of mail. Which was shipped two weeks earlier from child custoday court and was late and was torn up and opened. They also lock the place down early by 5pm every day so there is no chance to even get to your po box and get your mail. Save your money and get a po box somewhere else. Horrible service

USPS signs are misleading, 2 to 3 delivery or anything is not guarantee, the employees at Marshallton office really are bad and do not care. I waited to speak to post master for half hour and was no show, I had to leave. Use UPS or FedEx.
