Just as long as you send it out before Feb 28...you can ship whenever you want!
I ALWAYS send mine out when I get everything I've ordered...
IF I send out teasers...I don't announce it... Just because I don't want my buddy figuring it out before they get their gift! I'd wait until others start getting teasers...before you send your teaser out...just so you keep your buddy in suspense until they get their gift!
