I actually met a guy last night at redbox that said "I don't use codes, it's worth a dollar a night." That's $30 a month lost right there that he could be saving or paying for that outrageous gas price. That's one guy that will stay poor.
I have the same issue. I'm with AT&T but on a business plan. I have never recieved the text codes. Thanks to posting I have snagged over 30 free rentals.
In the location menu: I use Speedway gas stations in ohio. so far codes that have worked for all my cards are : breakroom, dvdonme, louzoo, taxes, apollo14, newyear, r7234h.
