I just tried this last night (without the promo code, just found that today, so will be going back to get FREE rental next time). I was excited about my great Kroger sale and decided to try out the movie kiosk in the entryway of Kroger. I had not tried Red Box or Movie Cube before but it was super easy and only cost $1.00 for a New Release DVD. Definitely beats Blockbuster's $4.99 price!
So why don't you try it out today? Use code ETUX9A9, which is valid thru 9/17. Go here for more information or to see the nearest location.
Thanks, Hip 2 Save!
