Any official safe website to SELL Korean and POP stuffs?

go to chinatown and you might find a store, if you can't order online from yeasia ( they kinda over price thier merch but they are fast and reliable) Kpoptown (cheaper and their albums come with posters but it takes about 1-3 days more than yesasia) Dvdheaven ( never used them but thier stuff is cheaper)
