Wikibuy

I don't know about you, but at checkout of any of my online purchases, I get to the Discount Code input and am annoyed. I know someone else out there has access to this product at a significant discount from the retail price I am prepared to pay. Maybe they know the owner? Perhaps, they are a VIP? Or, maybe they clipped coupons from their local paper? I don't know and don't care; I just know that I feel like a sucker without one. Therefore, when I learned about the Wikibuy browser extension, I downloaded and began to save. I'm not talking about $1-2 here and there; I am talking about $65 on my very first purchases! At check out, it automatically searches (who knows where???) for discount codes and then populates the deepest discount. It kind of feels like stealing ...  but is there a better guilty pleasure than saving money?
