Shared a house with some friends in college and we found a bug in a local Pizza place's site to stack coupons and get huge pies that were normally like $30 for $5, basically really good fancy pizza for cheaper than dominos. Really a blessing and a curse since it became breakfast, lunch, and dinner since it was hard to justify buying anything else.
