I sent 2 queen quilts for my great nephews in a flat weight box and it cost me 13.00+ for each one. With insurance it was $32.40 from Surprise, Arizona to Seattle Washington. I felt it was a lot of money added to making the quilts but we pay for it somehow. I was in a hurry as I mailed them on the 24th of Dec and they received them the 26th, so that wasn't too bad for Xmas time. I always weigh my stuff at home and try to print my own postage so I won't be surprised when I send it.
