Agreed, coupons are very old school in the age of Netflix, Hulu, etc. Considering they're a brick and mortar store with nothing in the way of online rentals, I'm pretty convinced there's no way they're making money.
That being said, I don't ask questions, I just step up to the trough for my free rental!
Not necessarily...redbox sends me coupons somewhat regularly for free rentals and stuff. Those are sweet.
