You probably already know this but Redbox is an automated DVD rental machine that allows you to rent DVDs for $1 a night. The Mcdonald’s near me got a Redbox a couple weeks ago. I’d read about Redbox before but until now there hadn’t been a Redbox close enough to me to make using it practical. Now it is providing me with very cheap entertainment. The rental is already cheap at $1 a night but after renting just two DVDs they sent me a promo code for a free rental. Doing a Google search for “Redbox promo codes” revealed even more free rental codes. Since the codes are good once per credit card by switching cards I should have free movies for the rest of the summer. The only drawback is I keep buying food at McDonald’s. Once I stop doing that this will really be a good deal.
