When sending USPS, If you are going to send your propeller by usps and i have to sign for it and I'm not here they will take it back to the post office. If we are real busy it might take us a few days to get your propeller. We have a new carrier and she will not sign for it and put it in my shop like my old driver. If you send it with out a signature required they will leave the propeller.
Thanks Mark
