This Friday only, Visa Signature Card holders can purchase any movie ticket from Fandango and then get a second ticket to the same show free! Go here to enter your zip and then click on the info to get your ticket. It will have you enter the first 4 digits of your Visa card number to verify that you qualify. Quantities are limited so be sure to purchase passes first thing Friday (or possibly Thursday night as it will be Friday on the East Coast).
