Not trying to be negative but it would be cheaper for me to go and buy my kids whatever was on the redemption shelf.
Yes, I know, but every year without fail you see people down sideshow alley at the Royal Show playing those overpriced clown/boatrace/coin toss games to win cheap novelty items that could be bought in a $2 shop and spending 10 times what the item is worth playing the game itself.
They key is to convince punters to think less about the actual value of the item itself and focus primarily on the challenge aspect instead.
