Poor seller. If they honor the purchases, they will lose hundreds, if not thousands of dollars for underselling the item. If they don't honor it, he will get lots of negative feedback from vendetta seeking buyers resulting in a bad buyer rating and thus preventing any further sales. The seller will then have no income to pay for his mortgage or children's schooling. He will likely have to sell his house for well below market value just to have enough money for food and motel rental fees until he gets back on his feet. Unfortunately, his wife will leave him for his coworker (who ironically happens to be an avid wearer of Terre D'Hermes Parfum and subsequently bought 25 bottles from the seller who mislabeled the price at roughly a tenth of it's market value). Spiraling out of control, the seller will then be forced to sell blood and bone marrow just to have money for food. Driven by depression he will likely turn to drugs, methemphetamine in particular. Within 6 month he will appear to have aged 20 years and won't remember how to spell his own name. People who pass him by will look on in disgust as he eats scraps of food thrown away in garbage bins. He may even run into his ex-wife and ex-coworker (who is still smelling of TDH) who will feel no sympathy for the fate that has befallen him due to his pricing error that fateful day on eBay. It all could have been prevented had one basenoter not discovered his error and amassed an armada of other buyers looking for a good deal on multiple bottles of that dry orange peel goodness. Ultimately it is the seller's fault for not bothering to check his price to make sure it was correct.
Either that or the prices are correct and everyone ends up happy
