I flashed my shiny LIVE Diamond card and the manager gave me a blank stare. Neither she nor the manager of the other nearest store has ever heard of the XBL Diamond program, apparently, but she had no problem accepting the coupon.
I don't know how well this bodes for Diamond, but it's worth a shot for you to print that bad boy out and take it to a Hollywood Video. I have found their selection is actually a little larger than Blockbuster's, if not quite as current.
And you can't beat a 2-for-1!
Do it soon, though--that particular one expires March 31st and I don't know if Diamond is going to pick up Hollywood again.
PS: if you don't have a PDF reader and want a JPEG of the coupon, e-mail me or send me a message here on XBA
