- JHJo HzJan 30, 20265.0Yes, there’s a line if you want services. Plan accordingly and stop complaining about something that is out of their control.
- JBJames BaldwinOct 21, 20251.0I went to this location to send off a priority mail letter. I asked to pay for priority and to have the ink stamps rather than using a book of stamps I intended to send in the letter to my mother. The worker said they could not do that, and that I’d have to put 13 stamps on the envelope. Manager subsequently came out to assist me and was a bit surprised I put 13 stamps on the envelope and informed me that I could have just paid to have ink stamps. The worker who originally assisted me then asked why I put 13 stamps on the envelope…

- CACraig AngellNov 5, 20165.0ALWAYS GREAT SERVICE BY ATTENTIVE EMPLOYEES
