I'm having fun reading what all the SS recipients received!
And for those who wonder where stuff is - as others have mentioned, people travel, the various shipping services aren't necessarily fast (my sister sent something on the 17th that arrived on 12/31), folk are offline during the holidays, etc. If you don't hear by Feb then it's time to get a bit irritated, but before then just go w/ the flow. That excludes the person who has said point blank they're not participating after saying they would (very bad form).
Cheers.
