Hi, if a person has entered a competition held by an organiser and completed the conditions, which is the 1st place winner will won $800, that was listed on the advertisement of the competition. But the organiser refused to pay $1000 to that 1st place winner when he has completed and won the 1st place in the competition. The organiser said there was a misprint in the advertisement and offer to pay that 1st place winner a $100 instead. Would the 1st place winner be able to sue the organiser for not paying the $1000?
