Hey fellas, just to let you know, there are two different medium flat rate boxes and you can order the correct box right here:

You order the box online and your mail carrier leaves it in your mailbox for you. You pay for it online ahead of time and print the mailing label and within a day or so the empty box is delivered to you. Once you have it and pack it up you can go online and schedule pickup of your package by your postal carrier. All you have to do is tell them online when to pick it up and where the box will be (in the mailbox, by the front door, etc). The last two times that I had pass around boxes here I handled it that way and it worked slick.
Thought I would pass this along as I am often on the road during the week and have no chance to go to the post office. It really helps out those who have exceptionally busy schedules.
