This is one of my favorite startups and they are hip and recently added FREE Bitcoins just for shopping on sites you already use. I'm a member of iConsumer and I think you should be too. It's completely free, you get Bitcoin when you shop online, save money with great coupons/deals, and you earn stock in the company itself. Join for free. Get 100 shares of stock in the company with your first purchase.
