Bottled Water Delivery, Anyone?

I have a coupon here that will give a new customer a $25 credit on arrowhead water delivery if you sign up for a 1 year contract and dispenser rental/purchase. In return I'll get a $50 credit.

Arrowhead charges $9/bottle, and we go through roughly 1 bottle per week at Entropy. I dunno what they charge for dispenser rental as we bought ours from Costco at the time.

Anyone interested in signing up?
