Even some brands like Dasani or Deja Blue are 1/$2 at gas stations
Also there's probably not a big price difference on their end. Bottled water is usually purified then remineralized to get a consistent product.

Not that there's anything wrong with that. Actual spring water is uniformly 45p for two litres:

That said, i imagine kevin_thibedeau was referring to the situation in the US. Perhaps bottled water is more expensive there. Or perhaps sugar water is cheaper.
Is that bad? People buy bottled water for the convenience, and because it's filtered tap water which tastes better than regular tap water.
If you want to reduce bottled water purchases you should advocate for a law requiring water fountains to have carbon filters for taste. (Although I kinda like knowing there is chlorine in there when I drink from one.)
I pay $4-$5 for 24 to 32 packs for Deer Park Water, which isn't tap water (but is owned by Nestle). $0.16 per bottle for spring water is incredibly cheap.
I'm fairly certain the parent was referring to the 24-unit packs of water, where each bottle is ~500ml.
The proper branded products have some distribution arrangements that mean you cannot sell their stuff at a low price, i.e. lower than everyone else. This is not 'price fixing' in a way the government can outlaw. Salesman from brand simply phones retailer's buyer and has a few words, implicit being the threat not to re-supply them. Large buyers will have negotiated a better price so long as they sell at the agreed price, clearly this privilege goes if they break their part of the deal, so next time they will have to buy at the official trade price, which is higher than what they need to make a profit.
Ma and Pa stores don't have the bargaining position - they buy from a 'cash 'n' carry' that might be supplied by another distributor (and an importer) all levels taking a percentage. They can stock 'off brand' products, but, even in a Ma and Pa store every square foot has to pay for itself, so why sell a low value, low margin, low $$$ turnover product?
Supermarkets sell own brand alongside branded products to present choice so you can buy big bottles of water at a price you would think does not make it worth them to stock. But check out the lunch purchases aisle, we are back to branded products at normal retail prices.
There is no conspiracy just capitalism and 'free market' practices. Having said that, water does have competition from a) the tap and b) the natural world. If you really wanted cheap water you could always run a tap (in the first world) or even collect your own rain water, filtering accordingly.
Makes a big difference. When we got our plumbing replaced I might get a whole house filter as well.
They rarely make any sense.
Just water a water filter for drinking water, with an extra faucet in the sink.
