For us, Amazon Prime Day is basically a national holiday. This isn't the first time the retailer has given us all these amazing deals, and at Prime Day last year, there was one product that reigned supreme: the famed 23andMe DNA Kit ($100, originally $300). This kit allows you to mail a saliva sample to the kit's labs and get results about your DNA in six to eight weeks. If you're interested in your ancestry, general health risks, or genetics, you should take this test, especially now that you can save $200! Especially as someone who doesn't really know their genetic history, I'm fascinated by who and what I'm made of, and clearly so many others are too! If you've ever been curious, what are you waiting for? This deal ends at midnight PST, so shop now!
