I have had much success with e-rewards. You earn e-reward money and you can purchase different discounts. I normally get the 6 free Blockbuster rentals for $25 worth of e-rewards, you get 6 coupons for a free rental each coupon is good for one month. It's great, I've never paid to rent a movie at Blockbuster.
