redbox

I have never used Redbox before. So tonight we thought we would try it, pick movie then pay, then I hear the machine running and nothing come out, then it just goes back to the main screen. Wife goes in to see if someone can help and they go you have to call Redbox. I call in and finally after...

So I see multiple Redbox machines around town here. Does anyone use them? Do they just take your credit card and give you your movie?
