Hello Tishi, welcome to FlyerTalk!
The deals listed at Bestfares, you can find yourself online. I was a member for two years (to give it a good try) and just did not see the value in it, because I could always find the fare offered (and quite frequently a better fare than what was listed).
Also have to agree with Jeffy FF's statement below.
