In CA they charge a bottle fee for plastic water bottles. If you can return those for a refund, I am unaware of it.
Depending on where you live. I live in Canada and my region you don’t get all your deposit back.
Then it's not a deposit.
The government calls it a deposit. The law that collects it and refunds it refers to it as a deposit. The charge on my receipt says deposit. The refund I get back is called deposit refund.
Except when I buy a can of Cola I pay 10 cents deposit. When I return it I get 5 cents deposit refund.
