RE: Need space!
When shipping in the flat rate box all you need to do is put a 1/4" piece of plywood on the bottom of the box, fill up the box, fill the rest of the box up with peanuts, then tightly pack another piece of 1/4" plywood on top. You will not have any problem's-as long as you pack it tight, and use extra tape around the sides. I sometimes ship lead ingots, with no problem. Tom.
