It happens in minor monopolies, which are exploitable best at small scale, like location or temporality. I can flip the latest Nintendo mini on eBay pretty easily. However, I can’t imagine the trouble that Nintendo would get into if they sold the same device at different prices based on zip code. Not to say that doesn’t happen, because that’s half the point behind custom phone contracts, where the price you pay for the device over time varies widely from person to person. Though, because it’s individualized, it’s very hard for consumers to compare one another’s prices and identify minor monopolies or price discrimination when it does occur.
