To me, have always had it minimized. I figure the chances of winning are so slim and I can't be bothered signing up for a whole bunch of spam or Facebook liking a whole bunch of products.
I also don't understand why someone would advertise a competition on here unless they were the one running the competition. In which case, you're just looking at a bunch of ads. Like if you were going to enter a competition, why would you advertise it and decrease your chances of winning?
But do people use it? Has anyone actually won any competition they came across on ozbargain?
I browse it when I have free time.
I've won a Weber BabyQ and a 2TB External SSD.
The people who advertise them are just community-minded legends (looking at you gnv9!)
