I've done my whole family and many of my neighbors too. It is $107.50 for your mtDNA(female) and $107.50 for your yDNA(male). If you have brothers and sisters you can share the cost with them, they'll all have the same dna.
See post #194.
I had the male side of my family tested. Came out R1b. Have now ordered the female side tested on the same sample.
