We have Blockbuster and now with Total Access you can return your online DVDs to the store and it will immediately clear your queue. Then you can pick up a free DVD in the store (return policy applies) and the next movie in your queue will ship. You can still return the DVDs by mail, of course. I think it adds even more flexibility.
With Total Access you are supposed to get just one Ecoupon a month, but my weekly one was in my account along with the monthly one.
I think they are still working out some bugs.
