Native speaker’s answer

K-Mart was a large store that used to be very popular in the United States. They were a department store that sold a little bit of everything: kind of like a Walmart. This type of store specializes in carrying a little bit of everything so you would only have to make one stop for certain items such as clothes, pet supplies, decorations, car supplies, etc. K-Mart is no longer in business and no longer exists due to financial issues.
