I often see posts on reddit about grown adults who buy entire pallets of newly released Pokémon cards or other toys just so they can make a profit by re-selling them online for a much higher price. I don't think I need to mention how pathetic this behavior obviously is, considering they are ruining an entire hobby created for children just so they can make a bit of money on the side.
However, most of these posts I see seem to focus on American stores like Walmart or Target, which makes me wonder if this is an issue only in the States or if this is also an issue here in Europe. Have you ever heard of cases of adult men and women almost fighting each other in stores in your country, just so they can get as many newly released Pokémon cards or other toys just for themselves?
