Noticing all of the Costco hot dog listings on the map reminds me: There's also an incentive for businesses to pose as users and misreport prices of competitors. My local Costco gas station constantly has a set of users misreporting the price of fuel, reporting the price as several cents higher than in actuality, seemingly in order to prevent consumers from refueling there. Something to watch out for.
