If you signed up through your online community, you can sign in to KPopupStore with your email address and one-time verification code sent to your email. But you can not browse the product sales page in KPopupStore but only access sales pages through online communities which are partnered with KPopupStore.
After signing in with your email and one-time verification code, you can only check what you ordered and what shipment address you used in KPopupStore. KPopupStore is not an online store for anyone. but is an exclusive popup store for the online community.
