Since I already had the pre-paid return label on the box, I was all set to drop it off at the UPS store, as the location I frequent also serves as a USPS pickup point (letters and boxes that are already labeled). When I walked by, I noticed this store was closed, but remembered that there is a post office in Streeterville (filed away from my earlier poke bowl expedition). Other than the fact that there were clipboard operatives outside from the Nature Conservancy, and being chided inside by the worker behind the counter when I was apparently not standing in the right spot, despite no one being ahead of me in line, I got through the experience unscathed. Given some of the security concerns around the blue letter boxes, it's good to know that there is lobby letter box for secured drop-offs. It also saved me a trip from going to the big post office downtown, a definite plus.

I had a PO Box at this Post Office... "had" being the operative term…read more Packages at my building were getting stolen at an alarming rate. Thus, I decided to get a PO Box so my merchandise could be stored in a secure, government building. Plus, I really loved that they have incredible hours, being open until midnight Monday through Friday, and late into the evening on Saturday and Sunday. Alas, this is the only good thing; everything else has been one issue after another. There was a major issue of packages seemingly not being delivered. I would see the tracking notification stating it was, but no 'package waiting' slip in the mailbox. I would bring this to the staff... some of whom checked in the back, while others stated that if there was no slip, it was still moving through the building. After this repeated enough times that some of the staff remembered me, and after I said "the only thing there is the cardboard on the back," he realized that the PO Box was effectively marked as vacant. Uh oh. It was removed, and I thought it would be uphill from there. Nope, there was a further issue. But first, a quick note about Street Addressing. PO Boxes at this Post Office come with Street Addressing, a service where your PO Box comes with a real street address. In trying to find out what this address was, most of the staffers had no clue what I was talking about. I eventually learned what it should actually be from a poster in the hall. Once I knew this from an official USPS source, and the "vacant" sign was removed, I ordered an item to that street address. The UPS tracking showed it as being delivered to the Post Office. However, the package was nowhere to be found. It ended up being a whole lot of finger-pointing, with the package seemingly being swallowed by The Void. After this, I decided it was time to close the PO Box. It was unable to fulfill the function I needed it to, and this is in large part due to negligence (i.e., not taking proper care) by this USPS. Final nail in the coffin: the number of letters that get lost, and the delays if they don't (about a month), are beyond unacceptable.

I only found out recently, as I had gone into the Starbucks to dispose of a coffee cup from another, nearby Starbucks (true story). There was one customer at the counter and another standing in line in front of me. The customer at the counter appeared to have a complex inquiry, but it was nothing that got heated. The customer standing in line was able to make use of one of the post office boxes mounted on the wall, so I catapulted right to the front. Despite the fact that there was only one postal worker at the counter, I was able to get my package mailed quickly and efficiently. I was provided a receipt with tracking info, and the package was delivered as promised. Definitely will be coming back here for routine postal matters so that I do not have to brave the Loop location that can at times be Kafkaesque.

This post office is located on the first floor of the Merchandise Mart, near the entrance closest to the CTA. No matter the time of day, the length of the line, or how many people are working, this place is always a shit show. As many of the reviews mention, it's so bad it's almost comical. You can't make this up. It's honestly the worst post office I've ever visited in my entire life. Heck, the one in my neighborhood now isn't rated the greatest but the service is one hundred times better. Save your sanity and go elsewhere.

Neither here or there I was upset because I was told that my package was here. The lady behind the counter with the no customer service face was blunt to the point. No your package is not here. We don't hold package at this location. Ok fine lady but do you have an idea Where? and what location I can retrieve my package? There was another lady behind the counter who was so kind to assist me and tell me that my package was over on Dearborn at the other location.

Do you know why I got myself a PO box? Mail theft at my apartment is rampant. If you order a…read morepackage, expect it to get stolen. One time I ordered something for same-day delivery, and even though I got there, an hour and a half after it was delivered, that package was already gone. Yikes. Hence, I thought I'll them shipped to a government building where it should be pretty safe. Now, I do want to mention, Amazon *can* deliver to a Locker or a Whole Foods, but not everything. Further, anything sent to me my non-Amazon can't go in a locker or Whole Foods. Now, while items delivered to the PO box would be held in relative safety, me getting it is another story. At the start, I found that packages weren't getting to me, with the clerk telling me that if there's no yellow slip in the PO box, then it hasn't been processed yet. Turns out, no. When the PO box was rented, cardboard was not removed from the back of it, which apparently signified that that said PO box was unoccupied. After lots of frustration, we finally figured out that, "oh, wait a minute, that cardboard shouldn't be there!" Okay, well now we removed it. I think it should be on the up and up from here, right? Not really. Not too long ago, I had a package that was shown as delivered and I came two days and some hours later to pick it up. I look in my PO box, and there's nothing. No package, no yellow slip, nada. I go to the clerk who tells me that after it arrives in the building, it takes two to three days to get processed. Really? After mail is delivered to the post office, it has to take an additional couple of days to get sub-delivered to the very same post office? Sure, it's a big building, but that doesn't make sense. Two more things about this location that have me pulling my fair out: 1. While to be fair, during my visits it wasn't super busy, there's usually only one or two people working behind the counter. 2. This post office allegedly has their street addressing service. That means that your PO box comes with a real street address you can use in additional to the standard "PO Box 1234 Chicago, Illinois." However, all but one of the staff seemed to have no idea what I'm talking about and what that address would be, even though I later saw it on a poster in the PO box area. Finally, if there is one area where I want to give them some points, it's that their hours are truly fantastic. They are open seven days a week, and on working days until midnight. This is perfect for me to be able to pick up my PO box items after work, even if I have to work a little bit late or if I need to mail something on a Sunday. Oh yes, and I almost forgot. The US Postal Service is kind of like Google... you can't really avoid it, unless you're going to send Christmas cards by FedEx. Just so, whether it's personally or where my job touches postal matters, it seems severe delays are as rampant as theft at my building.
