Ozarka’s bottle deposit policy is simple. On your first delivery, you are charged a deposit on the water bottles you receive. If you maintain that number of bottles, you will only be charged for water. If you order more bottles, you will be charged a deposit on the new bottles. If you require fewer bottles, you will receive a refund on the extra bottles returned. Never will you have a deposit amount more or less than the total bottles you have. The deposit amount of plastic bottles is $7.
