I'm going to concede on the particulars of how low the price was because it must have been just a killer loss leader in-store sale at walmart - the cheapest I can find now online is ~$7 for the same flat of 35 17oz bottles.

I am, however, going to disagree with how much water. 2 gallons of water for a single person each day seems to be more than just excessive for drinking water. Even if I was drinking 17oz each primary meal and another upon waking and upon going to sleep, that still leaves 171 oz remaining to reach 2 gallons.

Actually me and my wife went through approx 1 gallon per day, not 1 gallon per person, so approx 0.5 gal per day per person.

We use an RO filter, provides amazing taste.

Friend of mine spent 6 months sailing from Europe to and around the Caribbean and back. He said they planned with 0.8 gallons per person per day. That has some safety margin in it, of course, so 0.5 gal per day per person is likely bang on actual consumption.
