Why would one gain by keeping their wanton mee at $2.50 while everyone jacks it up to $3? You will net a greater pool of people, since you grab the people who are willing to part with only $2.50 to $2.99 in exchange for that wanton mee. Along with the people who are willing to pay $3 upwards. To simply meet the competitions' profits, you need to sell ONE extra wanton mee for every 5 each of you sell, since $2.50 would cover 5 lots of 50 cents extra profit your trendsetter is garnering. Possible? Not that hard, in fact.
