Update: Sale is live now. Not seeing the Mystery Reward button.
FamilyTreeDNA announced its 2014 Holiday Sale; sale ends 31 December 2014 (US Central Time).
The sale includes weekly mystery rewards. From the e-mail FTDNA sent out
Also, remember that the Mystery Rewards will randomly applied. That means that some females might get discounts for Y-DNA tests or Big Y tests. That’s intentional! In the spirit of the holidays, we want to people to share and exchange their Mystery Rewards.
I do not have this yet, but Roberta Estes shows what the Mystery Reward button looks like on her blog. The reward is for existing customers and can be up to $100. The discount is in addition to the sale price. The reward can be used by someone else.
For previous Big-Y testers, both Roberta and Judy G. Russell, the Legal Genealogist, mention a $50 coupon for another Big-Y test. This coupon can also be shared. For my U.K. viewers, Debbie of Cruwys News has blogged a similar announcement.
