- RRRTSep 19, 20255.0This is the best Post Office in Suffolk! Never a long line; the staff is very efficient. They respect your time, and know you have to get back to work. Additionally, they are always helpful and polite. If you picked the wrong box or there is better way to send it? They take the time to explain it. Plus the lobby is always CLEAN and smells fresh!
- SCS ConnollyJul 18, 20171.0I work very close to this post office. I got married recently so I have been in and out quite a bit with bridal shower invitations, thank yous, save the dates etc. It's a fairly small post office so I am usually dealing with the same two cashiers. Their body language, dirty looks and lack of happiness in their faces every single time told me they did not want to help me. I did my best to have patience. I'm sure selling me 150 stamps once a month can be quite irritating. But today...I am going to write my first Google Review. I got Hess on the phone this morning. I asked if she had a stamp in stock and she was pissed I would ask her such a question. That stamp wasn't there. So in fear of Hess's bad day, I timidly asked her if she had any other stamps that were appropriate for wedding invitations. She was PISSED! Finally I got, "Well we have the LOVE one". So, I said, "oh okay, thank you." and as I was asking her how many of that one she had, she hung up on me. I only write this review to let others know if you are looking to do any type of personal mailing go to the Wheeler Road Post Office in Hauppauge its very close to this one and you will have a good experience. They are amazing over there. Always helpful. They always have a large selection of stamps in stock and you won't have to be scared that the cashier is going to beat you up.
