Looks like if you haven't signed up for the water shipments at readyrefresh.com you'll get 50% off your first order if you sign up for recurring. $50 limit to the discount which would be $100 of water (wow).
Pretty solid deals, I got 144 of the 1 liter bottles (6 of the 24 packs) for $23.97 with free shipping and no tax because the discount stacked with the 50% off. No idea where I'm going to put them. You technically could get twice as much as me, but... yeah. That's a lot.
Here's the water I ordered (but it works on all water including sparkling):
Also, since I know someone will ask:
Hope you're thirsty. I've been needing to stock up on water since that legendary staples deal two years ago.
