A couple days ago, I wrote about getting a free rental from a Red Box movie rental machine using a promo code I got when I signed up and gave them my e-mail. Those codes can be used once per credit card, so if you had a credit card and say, a check card with a credit card company logo on it, you could use that code twice.
But wait, that’s not the only way to get free rentals. A quick Google search will reveal that there are several sites out there that have promo codes listed for Red Box. However, the most comprehensive site I’ve found so far is InsideRedBox.com. They have a comprehensive list of codes that are categorized by states confirmed that the codes work in, along with the ability to report a code, and if you register on the site, you can even track the codes you’ve already used.
This past week I can personally verify that I was able to use the multiple credit card tip and the codes to rent 6 movies without paying a dime. If you have a Red Box machine in your area, check it out!
