This is the lowest price we're seeing for any DNA kit at the moment. A DNA kit from Ancestry will cost you £79, plus shipping, as will a kit from 23andMe (also £79).

Living DNA is also running a sale with a £20 discount, but that still brings the price down to (you guessed it): £79, plus shipping.
