I recently bought a slab that was sent, without my knowing, signature confirmation. On the day of delivery, which I thought I was near, I was home on the couch and watched the mail truck pull up, wait a few, and then drive off. I went to the box and found a "sorry we missed you" tag in there. WTC, he never even got out of the truck . I did get the box the next day, but I prefer to have as few hands as possible on deliveries. It would seem to lessen the misplacement of packages. I am not a fan of signature confirmation, but if it helps ensure the delivery, I understand its use.
