I'm fortunate to have the legacy deal from BB.
1) Cost=19.45/month
2) 3 movies at a time/swap at the store for 3 and recieve the next in my queue (w/ no limits)
3) Coupon for two free games or movies each month
The trick...I find old TV shows I want to watch. I sub to the entire series, so I'm always getting something in the mail. I turn those in whenever I want a movie or two or three. I can always request them again if I need to. So, in essence, I've got TV shows I can watch from the past (I have NCIS season 1 right now) and can exchange those for anything in the store. I don't concern myself with what's coming from the queue, just what's in the store.
At 4 bucks a movie, it more than pays for itself after 5 in-store rentals per month.
