I'm on the unlimited one-at-a-time plan, and that's going up $1 per month, which isn't that bad. However, I'm annoyed that the only cheaper option I've been offered is unlimited instant viewing but no DVD rentals. I don't have the bandwidth for instant viewing to be practical, so I wish they'd offered me the reverse: a cheaper plan that's all DVD rentals and no instant viewing.
Go to the account section. Go to change membership. There's an option at the bottom.
1 DVD at a time (limit 2 rentals a month) (watch instantly up to 2 hours a month on your pc or mac--no netflix ready device or Starz) for $4.99 a month
