Resellers are individuals or businesses that purchase products from manufacturers or wholesalers and then sell them to consumers at a higher price. They often operate in various markets, including electronics, clothing, and collectibles. Resellers can use online platforms like eBay or Amazon to reach a wider audience and increase their sales. Many resellers focus on finding items that are in demand or hard to find, allowing them to profit from the difference between the purchase price and the selling price. Some resellers specialize in specific niches, such as vintage items or limited-edition products, to attract particular customer groups.
