Insert your plastic /glass bottles into the vending machine one at a time. You get $ 0.05 cents for each, size under 24 ounces. After you are done, machine will give you a ticket with the value of $$ you’ve earned and just take that ticket inside Food, Co. Grocery store to redeem the $$ from the cashier(s). Very simple and kinda cool to take part in helping the environment! :)
