This is the current FTDNA offer and a tremendous deal. For YDNA, the minimum genealogically relevant test that you should go for is a 37 marker test, 12 markers to get started if that is all you can afford, but this deal is barely above the 12 marker test cost and includes mtDNA as well. You can obtain the sale price through any Surname Project. Y-DNA37+mtDNA for $ (only a bit more than a 12 marker test's normal price). ( – a reduction of more than 50%!!) • The promotion will begin on June 9, 2009 and will end on June 24, 2009 • Kits ordered in this sale must be paid for by June 30, 2009 Good searching, John Carr

The Y-DNA37+mtDNA test listed on http://www.familytreedna.com/products.aspx is $399.00. What's the difference for the Lewis' test kit?
