If your favorite beauty product was discontinued, it might not be gone forever! Send what's left of your lipstick—or blush or eye shadow—to Three Custom Color. If the sample is at least the size of a dime, the company can match the shade (it has more than 9,000 colors in its archives to work with). For Estée Lauder brand products (like Bobbi Brown, Clinique, Origins, etc.), call Lauder's Gone But Not Forgotten program at 800-216-7173. If the item—excluding limited-edition products—was discontinued within the past 36 months, the service will search for ones that remain in its inventory for you to buy. Pretty useful, right?
