Last week I was browsing the web and found an awesome travel site, but I never bookmarked it.
You would basically pick the week you were looking to fly and it would tell you all of the e-savers and deals from basically every airline (namely I remember searching and finding all of the jet blue destinations that were $99). I love kayak but that is not it, nor is it any major known travel site. I saw it on some top 50 or 100 list, had never heard of it and it was incredible.
