Merchandise is like toys or snacks that people can buy. Sometimes it has a special picture or design on it, like a cartoon character or a sports team logo. Merchandise can be found in stores or online, and people buy it because they like it or want to show support for something they love. When people buy merchandise, they usually have to pay money for it, just like when they buy other things they want or need. It's like a little souvenir that reminds you of something you like or a fun time you had.
