Maybe one of the weirder deals - 23&Me in celebrating DNA day with a one-day $99 special for genetic testing. Today better than the $500 I paid and the $1000 it cost when I got it half price.
I did it about a year ago and it's actually pretty cool and they satisfied my privacy concerns. This stuff is pretty early in its development, but about the fullest testing you can get under $250,0000, and you're updated as the research comes in.
