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.
