N.Y. Gen. Bus. Law § 399-O
Every person, firm, partnership, corporation or association which sells, offers for sale, or exposes for sale at retail an item for which the seller is required by state or local law, ordinance or rule, to collect from the purchaser a refundable deposit on beverage containers, shall not include the cost of the mandated deposit when displaying the selling price of the item through item pricing tags, point-of-sale signs, advertisements, or any other means by which consumers might be informed of the cost of the item. Nothing in this section shall prevent the seller from separately indicating the amount of the deposit provided, however, that the deposit is excluded from the indicated total cost and it is appropriately identified as a deposit.
