Wow, another FREE rental code. This one is for 1 FREE rental from Blockbuster Express. The promo code you use at check out is 21CHD3X. This code is good until January 28th, 2011. I have not personally tried this code. Please send me a comment if it doesn’t work. This is one I found online. If I ever learn of a code not working I will update the posts. Thanks everyone. Hope you all have had a great weekend!
