The Mailbox Shop is just like any shipping center - boxes, packing peanuts, scales, and tape. I've been here 3 times, mainly to get boxes to ship stuff since I don't exactly have a plethora of different sized boxes. They did the measuring and box selection. Cost seemed reasonable for boxes and packing material. I did get the feeling that I was more picky about packing than they were - they were content with just tossing in whatever and so be it whereas I wanted to make sure the item didn't shift, etc. So if you're shipping something you value (or valueable) you may want to pack yourself.
