I mailed a California king quilt to Texas as a surprise gift to a friend and mailed it USPS. I insured it for $750 and was told that since the insurance was over $250 that they automatically would require a signature and would not deliver it without one. When my friend got home, the box was on her doorstep, no one was home. Luckily it was not taken. I talked with a postal service person here and she said that if I still had the paperwork, they would send it down to Texas and have the paperwork show it was not signed for, and that the carrier would be disciplined. I could not find the paperwork, but since she got it, there was no foul. Just keep your paperwork until the quilts have been delivered.
