23-and-me one-day sale

23-and-me gives you information about your own DNA. I just became a customer. They're running a sale.

Normally, it's $199, plus a $9 a month subscription to updates for a year (after which you can continue to subscribe or cancel).

Today only: you still have to subscribe, but the $199 is waived, so it's about $100 instead of about $300. I'll find out whether the subscriptions are worth it over the next year.

Note that Federal bureaucrats want to shut them down because they think your DNA is something that only an M.D. should explain to you. Even without that, though, I'd have still bought it.
