    My last 2 package deliveries were delivered to the wrong addresses in Marion. Latest one delivered across the street. I dread ordering something if I know that USPS will end up delivering it. UPDATE: Another order from eBay not received. Image appeared in my USPS Daily Digest email but package not in my mailbox. Phone calls made throughout the day go unanswered.

    Recently drivers have been placing are male outside on top of the packages. Twice now I've come home to soggy letters and this time I received a check, which got ruined by the rain. Widely unacceptable.

    I love this post office!! I ship many packages sometimes daily! Almost all from williamson post office. The other reviewer was right about the boss she does have a bit of an additude but she is always polite . I usually work with one of the counter people instead. Frankly they are amazing!! They do my best to help me ship the cheapest way. Things ship quickly and get where they are going! They even buy suckers out of their own pocket so the little guys can have one (my kids love this)! This store really is a gem!!! Love going here!
