No one reads those!
You just see 'chance to win free stuff' and sign up.
I think Super Liquor copy & paste a lot of the T's & C's from other promos and probably don't read them properly themselves.
Can't imagine there would be too much dispute over the identity of an entrant for a competition like this. Certainly be important if the prize was a considerable value though.
It's funny. I read through the Terms & Conditions and it says, "In the event of any dispute over the identity of an entrant, the winner will be the person who is registered to the telephone number used to enter? Hmmm, but nowhere on the entry does it ask for your phone number. (shrugs) Am I the only one who read the T&C's? Probably lol.
