From time to time as I am notified or find genealogy related items that are "on sale" I usually post an article for those who might be interested. For me, unfortunately I get no cut in that action, perhaps I should look into that.
Anyways, Ancestry.com has a sale on its DNA kit for $79 with free shipping. To get this great price and free shipping (usually about $8-9) use the coupon code FREESHIPDNA. Additional kits are $69 each. The coupon code expires soon so check it!
Check FamilyTreeDNA.com for their 20% off sale on the various FamilyTreeDNA kits.
