Carnation, Wa. USPS went above and beyond the call to duty for me. I ordered a Christmas gift and living in a rural area with a POBOX, I use both addresses, since I never know which company will be handling the delivery. The company I purchased from decided to only use my physical address, where I don't receive mail. Somehow Carnation PO rescued my package and put it in my PO BOX. Yes, Virginia there is a Santa Clause and he sometimes wears a Post Office uniform

The employee at this post office was incredibly kind and helpful to me. I was sending a small amount of my husband's ashes and was able to get the correct box and tap for it. She was patient and worked through some of their system's issues for processing. She got everything handled so I could get something made in honor of my husband. I am so appreciative of this employee and location. Definitely visit them instead of the Duvall Post Office.
