A new promotion from Redbox begins February 1.  Rent two DVDs at a Redbox kiosk at one time, and you’ll receive a promo code by e-mail for a free DVD rental. You must fill in your e-mail address to receive your free promo code. According to the fine print, you must rent two movies at once without using a promo code to pay for them (each rental is $1, so it's a $2 investment).  Don't forget that after Redbox sends you the promo code for your free DVD rental, make sure you use it within one week, or it will expire.  This deal is good through February 14.
