These guys are similar to expedia in terms of services for booking tours and attractions around the world. Was booking a tour in vietnam and came across this code for 7% additional discount. Not sure if it is general for all bookings. Probably is.
Update: Credit to Schumi5 for following detail:
You will find you will need to go via this link to get the discount

otherwise if you go straight to the viator website and enter the code it wont work.
pretty good deal though,
