Costco is a biggest wholesale corporation which is membership only. The head office is in Seattle. People have to be members to shopping at Costco. The cost is 4200yen. They sell food, household goods, clothes, furniture, jewelry and so on. They sell these items big size, and good price, so people can buy something many and low price than other shops. People can enjoy not only shopping but also eat food here. When I went there, I enjoyed shopping and had pizza. The pizza is cheap and good taste. There are 15 Costco in Japan. If you live nearby Costco, I recommend you to go to Costco!
