- WRWhitney Rose3 days ago5.0I dread going to the post office. The employees that work the front in Affton are exceptional people that remain kind even in the craziest scenarios imaginable. Thank you for that. I see you guys really try to help people that struggle with the mailing process and it doesn’t go unnoticed.
- SJScott JacksonFeb 9, 20265.0I was in line in and out quickly. Well maintained post office.
- JBJeff BaileyJan 28, 20261.0This is January 28, 2026. I just had open-heart surgery. I was released Sunday, 18 January and why are you all not delivering my mail? Is it because of the snow plows that pushed a little bit of snow in front of the mailbox or what this is ridiculous I don’t have nobody to help me and I’m not getting my mail also.
- KAKelmend ArifiJan 24, 20261.0Costumer service is terrible, and they treating people like slave, don't go here, they yelling on people and attitude this is insane
- DADerek AlbrachtJan 23, 20265.0I'm the first person to write a bad review for bad service. But I'm also the first to commend those who are trying to do their job. I've put in multiple requests to the USPS website for packages that have been stuck or potentially lost in the black hole of St. Louis USPS distribution centers. Just yesterday, I did put in such a request about a package that has been stuck at the same distribution center for a week and still hasn't been delivered to an Affton address. To my surprise, I received an immediate call from Jefferey at the Affton Post Office. I was pleasantly surprised at this. While not the Affton Post Office's fault for the package being stuck at the Hazelwood distribution center, Jefferey called to let me know they are doing everything they can to get the package delivered. Thank you Jefferey for your help and quick response, even though it isn't the Affton Post Offices fault.
