Idea of the day: Omni-Membership   

Although Groupon is trying to help online shoppers save a few bucks here and there through collective discounts, I have to wonder isn't there a better way to do this?  I think Amazon Prime is onto something great, but could it be better?  I imagine that someone is probably out there and thinking about forming a company that would bundle almost anything they could into one subscription-based program which is similar to Amazon Prime but better. So, imagine when you go to the movie theater or eat out or shop in a mall or go online or whatever, you just have to be authenticated as you who is a member of this omni-membership and you automatically got a discount.  Wouldn't this be way easier than having to pick out a discount yourself on Groupon?  Obviously, this would save you time.  If this could also save you a ton of money, this is definitely a way to go then.
