Your local supermarket probably sells gallon jugs of filtered water for $1.00 or less. Use that for drinking and cooking, and tap water for bathing and washing dishes.
Well, I thought it was funny.
Thank you. 
I actually do drink bottled water, but I get it from Costco which is something like $4.50 for 15 liters, which is more or less reasonable considering anything less than “spring water” tastes funky to me.
My local supermarket chain is trying really hard to convince it’s customer’s it’s an “upscale” store, so they’ve started carrying more ‘upscale’ brands of things, more “Natural” choices, etc.
Just recently, just wanting some cheap spaghetti sauce to use in a recipe, I noticed certain jarred pasta sauces in the store selling for ~$10.00 a jar!! Ten bucks a freakin’ jar for pasta sauce? What the hell is in there? Heroin?
I’m with you on the sticker shock, but dang, that stuff works wonders.
In the same vein, a plastic refrigerator drawer costs $85. Ended up fixing it (rail had cracked) with duct tape. Works like a charm.
Oh, it’s totally worth it, but when I first opened the box and that tiny tube fell out…
The TAP?!?! Well LA-DI-DAH! When I was a kid we drank it straight from the hose - it burned our lips too because it’d been lying in the sun all day!
