I can rent a movie at Family Video at $.50 to $2.00 for up to three nights which is MORE than enough time to watch it. The best thing Blockbuster has going for them is their "no late fees" policy which really doesn't apply to me as I generally don't rent a movie unless I'm going to watch it that night or the next day.
Also, if I really need to, I can just get my movies for free at the library for the same amount of time (sometimes longer).
