KR Multimedia does their marketing on their Facebook page. They post new shipments, preorder options and post about hosting events to trade photocards. I love the kpop community that this shop holds!
Overall, I absolutely love this shop! They have the latest releases (newly released albums come within a week it seems), reasonable prices and very friendly and knowledgeable workers. I can't wait to stop by KR Multimedia again for my kpop fix! Also I'll post my mini haul from KR Multimedia soon, so stay tuned.
