Not sure why he posted that, but for someone to know conclusively what was in the package, without being the recipient or sender, is just speculation.
It could be promo t-shirts. It could be missing parts for a bar-b-q. It could be a book of the month club. I ordered a new cell phone and it was a signature only delivery to my house. I missed two deliveries and had to pick it up in person.
What I do know is that it is not likely legal stuff, as that would most likely be delivered to SRFF.
Personally, I think it is a cheesecake or similar desert from honeybaked ham. JMHO.
