Except the stores which enforce a fixed-price system,,,like department stores.. you can ask them some discounts...( 깎아주세요 ) It would be easier if you buy more than one or two items or pay in cash.. c.f) http://www.sayjack.com/korean/sentence/2252/. http://blog.daum.net/liralira/6250705

Thank yoooou!^^

Bargaining is slowly disappearing in Korea. Now days most of the stores have fixed prices even in traditional markets! But if you buy several items you can always ask for a discount. In this case sometimes they will even give you a discount without asking for it!. But if not, here are a few useful phrases to ask for a discount in Korean: 깎아 좀 주세요 (cut the price please) or 조금 싸게 할 수 없나요? (can't it be a little cheaper?) Another useful phrase is 서비스 주세요 to get something extra for free.
