why do you want a korean store? overseas stuff has ridiculous pricing unless you're buying when you're there.
Try www.zipia.net but you have to order for 500 dollars at least...they really have nice things...and its not really expensive...just the shipping costs alot...
Ebay seems to be the cheapest way to go, but their stuff might not be as good quality, shipping is mostly reasonable though unlike some other online sites
ahh! I was going to say that lol it has brands from hk and japan, they also have a china section, but the last time I checked there wasnt anything in it yet =( I bought some really nice things there lol I really like that site.. zipia is nice too, just have to get use to how they set up the website..abit awkward at first, in my opinion.
zipia cct-fashion je551 gmarket.co.kr [Korean, this has more] global.gmarket.co.kr [English, this has very limited items and it's the more expensive ones too] mmm that's all I can think of for now. There's a lot more though
