At first I didn’t believe it when I saw it. Costco in Korea? After a double take, checking the font of the signage, it was confirmed. They’ve partnered with Samsung (=Shinsegae, E-Mart, Starbucks, more) and have 6 stores in Korea, 3 in Seoul. Membership is honored worldwide, renew here because the annual fee is cheaper in Korea (35,000W per couple). You’ll find about 1/3 the products you would see in a stateside Costco with an identical food court (hot dog!). FYI: it’s the only source for peanut M&Ms, trust me I looked everywhere. Tip: bring cash (ATM in lobby) because they only honor Samsung credit cards.

Multi-story Costco in Seoul should be avoided on weekends.
