I think all of the tests and even the upgrades (eg. From 12 to 67 markers) are marked down. For example, the yDNA 37-marker test is reduced from $169 to $119. Family Finder (autosomal DNA) is reduced from $289 to $199. So if you’ve been thinking about it, now’s the time!
As an affiliate, I don’t get a commission for tests that are under promotion, but please use the Family Tree DNA links in this post or in the sidebar anyway so I can track clicks. This is an end-of-year sale, so tests must be ordered and paid for by Monday, Dec. 31 to get the reduced rates.
