From what I recall from a bioinformatics course, I really doubt you can have your DNA fully sequenced for just $200. But, prove me wrong, do you have some resource saying otherwise?

Nebula offered specials for full genome sequencing.
They’re now owned by DNA complete.
DNA Complete prices it at 495. I paid half that for 30x.
“By analyzing your DNA multiple times, we can significantly increase accuracy. 30x Whole Genome Sequencing means that 100% of your DNA is sequenced an average of 30 times, thus providing even higher accuracy. Typical DNA Ancestry tests sequence less than 1% of your DNA.”
