“(discount-wall layout -- dense grid of time-limited deals without sourcing or quality context)”
A page of aggressively low prices with no explanation of why they are low triggers counterfeit and quality concerns. Japanese consumers are particularly quality-sensitive; a deal that looks "too cheap" without sourcing context gets dismissed as fake or grey-market.
“Anchor the pricing: "Direct from Korean brands to you -- no import middlemen. Authentic products, Qoo10 buyer protection on every order."”
Explaining the supply-chain reason for low prices (direct sourcing, no middleman) converts suspicious browsers by reframing "cheap" as "efficient" -- the same logic Costco uses.
