Refunds on water bottles and jugs
You don't get a refund. We learned the hard way that you have to pay a deposit if you don't have an empty bottle to exchange. You get a discount off a new bottle with an empty exchange, but you can't get your money back just for an empty bottle. Not sure yet why. We used to get our deposit back when we had it delivered to our house.
The exchange was good no problems
About $13 new. $6 if you exchange an empty container for a new one.
Why are you paying $7 for 5 gal of water? Take the bottle you already own and go fill it elsewhere, for between 0.30-0.60 per gallon, I refill at Winco or Fred Meyer grocery stores.
