I've seen commercials for search engines for Kayack, not so much for Expedia or Orbitz anymore but I would like to ask, do they really present savings for travel? What was the best deal that you received from any of these travel search engines? Was it on hotel, car rental? Did you receive a coupon that needed to be presented? Was prior registration or a confirmation necessary? Just how do they work to receive the discounts? I'm very curious.
