This is the same deal you get when you interview with Ancestry. They give you a coupon for 50% off a DNA test.
The results are very interesting, and the more people that take the test, the more accurate your results will be. So you can login every few months and see if there is new data.
How often does this go on sale?
We had it in a woot-off and this was remaining inventory. Not sure when or if we’ll be running it again. Sorry.
