I don't know if this is for northern california only. But if you purchase two cans on coke at your local 7-11, 81cents each. They give you a coupon for a free rental at your local blockbusters. All you need is the receipt and the coupon. I guess $1.62 for a blockbuster rental is not bad. Anyways one coupon per visit. I don't think it's valid on dvd's, someone go try.
