Since launching in 2012, Ancestry DNA's database has grown to hold almost 10million DNA customers, easily the world's largest. As such, it statistically offers the greatest chance of matching with the descendants of your extended family.
The company's DNA DAY sale offers at least 25% off the regular price of its DNA test kit, which varies according to the area of residence of the person taking the test. (There may well be additional offers via Ancestry.ca and Australia.com.au, and other countries but I haven't been able to find them due to Ancestry's bloody-minded geo-locator.)
The prices below do not include shipping, which is extra.
