Shhh, I'm retired, running a little business on a part time basis.
When I ship product, I use United Parcel Service or Federal Express.
You can order mailers from them and they will deliver for free. It's a great deal. This way you don't have to subsidize the tit-sucker based Post Office headquartered in Washington, DC.
