No. There are many convenience store around my room - 7/11, G25, CU... and no one offers this kind of service. Yes, some offer it, but it's the exception, at least in Busan or in my district. Maybe it's different in Seoul? In Japan, yes, 7/11, Family Mart, Lowson, they offer it everywhere.
In Korea ? And it's not 100b but 100w !
