I have good experience with Scoopon.
Got six scoopons on this offer for $69 for the ULTIMATE Full Day Adventure Pack which by Great Sights! Includes Australian Reptile park, Dolphin watch,4WD and Sandboarding, entries and activities INCLUDED! Normally $166!

It actually ran by Grayline, same as http://www.grayline.com.au/australia-sightseeing/sydney-day-…
Found it excellent value,no different from people paying full price, easy to book, easy to change the day.
My experience is tours are alright, especially by Great Sights(in my experience), but food and service I would avoid.
Oh! No, I have nothing to do with all those companies-> Scoopon, Great Sights or Grayline. Just want to share some positive experience!

what?! a non-scoopon hater!? GTFO!!
just kidding. i havent had any problems with scoopon either, but i also only buy food type deals and not service type deals (yes food is technically a service but you know what i mean). i also make it a point to redeem my coupons as soon as i can after purchasing which i attribute to my success :)
