I joined many years ago because that introductory offer was too good to pass up, but after a while, I didn't have a lot of movies that I wanted to collect anymore! They have an automatic title that is shipped to you every month and they're not the best titles unless you're a real collector. When I started getting titles with those puppies doing sports with cheesy voiceovers, I realized I had just about enough.
A word of caution though, like any automated service, they make it difficult for you to cancel. It took me a while to find where I had to go or who to call before I could cancel my account. If you're into collecting Disney movies and can manage the titles you want each month, then it's a great service. You might be able to find better prices elsewhere though it's been a while since I was in the program to know if they lowered their prices. Hope that helps!
It sounds interesting enough!
