How does that work?
Same way most movie clubs work.
You get a bunch of movies for a cheap price and then you have to buy 3 more over the course of a couple years (usually at 21.95 a pop, plus shipping).
They automatically send you their Feature Selection once a month, but you can go online and opt out of it.
I used to be in both Columbia House and Disney, but now I just stick with Disney since they let me know when classics are being re-released and I can get them delivered before they hit stores.
