Be extremely sure you want this, because per their TOS the return is the price you paid minus around $25 for the spit kit. Even unopened kit won't be accepted/money refunded, I was told via their helpdesk.
The thing that got me to change my mind was some blogger article that was going through their TOS/PP and realized that once you do this test, you are legally obligated for revealing results to the insurance company you plan to be insured with. Not sure how much the truth it is, but this plus the owner sleeping in one bed with Google's Brin ("hey honey so how is it going with collecting peoples DNAs? - very good - okay keep up the good work, in couple years I will buy you out then we can match your DNA database with their credit card / name / dob and attach it to their Google profile so we serve them more matching ads", turned me away for good.
