McDonald’s How Do You Frappe Cards

Jennifer over at Confessions of a Couponer was given a card today at McDonald's. It is called “How Do You Frappe?”  On the back it says, “Drinking Frappes can be rewarding.  The first one is on us.  After that purchase 4 and get your 5th small Frappe FREE.  Keep your card and buy another 5 Frappes and get the 6th small Frappe FREE.”  This card expires 12/31/10.
Be sure to ask at your local McDonald’s if they are doing these cards! Let me know if find this!!
