CostCo... if you do not know what that means, then maybe this store is not what you are looking for.
All goods are sold in bulk, but they key here is that they are western goods... the items that are hard to find in Korea.
What to buy: All goods from back home are available... including those somewhat harder to find items, like Turkeys near Thanksgiving...
What to pay: Average western prices, but possibly 'slightly' inflated.
Similar to Costco back west, membership card is required.
Simply put it is a Harley-Davidson shop. There are two stores in Korea, one in Seoul and one in Daegu. If you have a bike, this is the only place to get parts. If you like their clothes is the the only place to get genuine HD attire
What to buy: The clothes are mostly for the local Koreans. You better search for a LARGE and make sure it fits.
Most local Koreans do not want any clothes that have "Daegu" written on them, but they rather prefer stuff that says USA... so again, if you want something that proves that you were in Daegu, they do have them, but the choices might be limited.
What to pay: The clothes here are expensive, mostly because you are paying for American brand names. A simple t-shirt costs $45US
