Biologists estimate that water makes up 65% of the human body, 71% of the planet’s surface, and 0% of the R & B group Earth, Wind & Fire. Conquer the planet’s most prevalent liquid with today’s Groupon: for $49, you get a six-month water-cooler rental package from Culligan (a $256 value). Each package includes:
- Water-cooler rental (a $10 value/month)
- Four 5-gallon water bottles delivered each month (a $7 value/bottle)
- All bottle deposits (a $7 value/bottle)
In business for more than 75 years, Culligan purifies its gallons of water with an advanced reverse-osmosis-purification process that banishes sodium, lead, chlorine, and other impurities. Deliverymen truck four jugs of the hydrating potation straight to households each month, providing enough refreshingly clean drinking water to adequately fill a pet walrus’s aquarium. A handy cooler system makes water easily accessible, and a regular pickup service carts off old jugs and recycles them as makeshift conga drums.
