Why do we not have a after hours drop box, Buttermilk has a awesome one. You can drop up to a 12"x 24" box including purchase postage.


I had a package I have been waiting weeks for supposed to come today per notification. I was having fence installed and apparently truck and trailer which were very long were blocking mailbox so that did not happen. You know sometimes things have to be brought to door cause the don’t fit anyway. Would it have hurt you to get out of truck and make an effort to deliver. It was not a personal vehicle causing the block. Geez.


Hello, I was supposed to get a package delivered to me today with the order name of Scott Robinson, yet both times I went to get the mail there was no package. I ordered from amazon and it said it was delivered. I would like to know when the packages is coming. Please and thank you!
