Family Tree DNA special until Feb 28, 2013! $39.00 for a 12-marker Y-DNA test.
This helps make DNA testing affordable so if you've been putting off ordering your DNA kit, now's the time. The beauty of this is that you can wait until you see a sale for an upgrade and then start getting more and more markers tested.
See my other blog posts about testing my brother's Y-DNA and the upgrades (67 markers, Family Finder, etc) I've ordered by going to my posts under DNA JOURNEY
I've had my own mtDNA tested through Family Tree DNA
And I've ordered my brother's and my DNA tested through 23andMe. It's been an interesting DNA Journey and it's not over yet!
