In the context of buying and selling goods, a scalper is someone who buys things when they first go on sale and then sells them later at a higher price. This is usually done with concert tickets, sports tickets, or other limited items that people really want to have. For example, a scalper might buy tickets to a popular concert as soon as they are released and then try to sell them for a lot more money closer to the date of the concert. This is generally considered unfair because the scalper is taking advantage of people who really want to go to the event but may not be able to afford the high prices.
