Eli5- How do they make profit on bottled water

Question

Hello,

We have bought a pack of bottled water at Costco, it is 35 bottle of 500ml, the entire pack was 2.75 Canadian Dollars.
How do they make profit on this, it’s about 8 cents per bottle, that would include, the water, bottle, and printed paper on bottle.
How do they make it work ?

Thank you

Update: I did some Googling, it’s indeed spring water, and not tap water. Check here: https://www.cbc.ca/amp/1.3825916

You go there to buy the cheap water and while you are there, you stock up on toilet paper and cheese curds.

A customer in the store is the goal))
