Dunstan

The art of low-balling sellers when buying an item, and then reselling the same item on the same Facebook page for more than double what you paid and abusing people who offer substantially less. People who commonly practice the Dunstan tend to avoid being detected by swapping items for items of higher value or posting up EOI ads and asking people to inbox them for the price in hopes that said person didn't see the advertisement when they bought it. Another classic example of the Dunstan is purchasing a complete car for $1,500 then asking $1,600, $800 and $500 for just three parts off said car. Some people who are religious believers in the Dustan will lie about what they paid for the item to give people the false impression that they aren't profiteering.
