Celebrating reaching 15,000 fans on Facebook, FamilyTreeDNA is having a 36-hour sale on their genetic genealogy tests. FamilyTreeDNA has previously had sales when they reached 5,000 and 10,000 fans. Unlike those earlier sales, there is no special code needed for this sale. Discounts are as much as $200 (for the Comprehensive Genome bundle).

I’ve previously written about using genetic tests for genealogy, first briefly when FamilyTreeDNA had their 10,000 fan sale, and then again in more detail in my article Using DNA for Genealogy: Y-DNA and mtDNA.

The sale ends midnight on Tuesday, September 27th (Central Time).
