I did the Ancestry DNA(a few surprises and a reminder that my grandfather was half jewish) a few years ago and I think I am going to do the 23 and me with the health next. This video was a good reminder to look out of deals.
Hey there! I don't have any inside info on sales for 2021. But I think it's reasonable to expect there will be sales around the same times that they have historically had them. Right now there is a 20% off deal for 23andMe Health & Ancestry Kits for Valentines Day. I'd bet that you will see sales in April for "DNA Day" and then usually after that there are deals for Mother's & Father's Days. I've even seen St. Patrick's Day sales in the past. I hope this helps, cheers!
