I’m not sure if they are going to limit how often you can change your subscription but since I watch mostly streaming I will keep that. Since there are very few Blu-rays (mostly new releases) or DVDs I rent anymore I will just drop that until a sufficient number like 8 or so are available I want to see. Then I’ll just upgrade to one at a time with Blu-ray order them and then chancel before the month is out.
I use to do jump back and forth between 3 at a time unlimited and 8 at a time unlimited before without a problem.
