I think the rule last year was "don't be a shithead"
I kinda broke that rule (although it wasn't completely my fault) but I'm making up for it this year.
I made the mistake of ordering something online and having it shipped directly to the person. I figured everything was fine until I got an email in mid-January telling me that the order never shipped and they were refunding me. I think it was shitheads.com. Should have known better.
So if you didn't get anything last year I'm probably the shithead that didn't send it to you. I've banished myself to my own personal hate pit and will be re-sending an even better gift this year.
