The link in the previous post takes you to a page where the DNA kit is $79. I spoke with someone at ancestry and was told it depends on the length of time you have been registered with ancestry and other nontangible factors. With several friends ordering yesterday and today, I am not sure this information is correct.
If you are interested, I would call 1-800-ANCESTRY and ask why the special of $49 does not appear for you. Also ask about FreeShipDNA.
I did order my kit this morning at $49
