I am not really sure what the solution is to this but I wanted to tell you what happened to me. I was expecting a package from an eBay seller and I knew it had a signature required. I saw the postlady come up the walk so I opened the door. She acted surprised and told me she was going to leave it on my porch and asked if that was ok. I wasn't sure why she was going to leave it on my porch since I was here (too lazy to ring the bell?) and she started to leave. I asked if it required a signature and she said yes, that SHE had signed for it!!! As the buyer, it didn't really affect me but if I were a seller and she did this on an expensive item, I would be mad! Any suggestions on how to handle this?
