I saw a USPS counter guy take an oversized item and take 2 large flat rate boxes, slide them together so one was inside the other and he taped it up so it was about 4 inches longer total. I think he just didn't give a rip anymore. Wonder if that item made it....I ordered a whole bundle of the large "game" box sized boxes, they were delivered for free in 2 days on my doorstep. I used a few under the pan of my slow oil leak truck.
