I found the $1/3 Perrier Mineral Water  from Coupons.com under zip 02911. I’m not a big fan of mineral water, but I know people that swear by it. I do know that it is AWESOME for getting food stains off of white shirts! I just haven’t acquired a taste for it.

 Perrier 750 mL: $1.50
Use $1/3 Perrier Mineral Water
Total: $1.17 each!!
