Pretty sweet idea. The video is a bit long, but it's a good story that makes a good point. What happens when consumers organize their collective spending to negotiate with retailers or service providers? Well, it turns out, they can get more than a good deal, they can make a difference in the community.
Carrotmob is a group currently forming in San Francisco whose mission is to do just that. Their model is basically to create a bidding war between businesses who will ultimately benefit from a flashmob of purchasers. The great part is, they are bidding on how much of the impending proceeds the store owners are willing to commit to making ecological improvements to their own store.
It's a true win-win and its pretty scalable.
