This spreadsheet is built around KakoBuy because that's the agent the curator uses: warehouse photos, coupon stack, and a checkout flow that doesn't fight you on mobile.
CNFans and other agents can buy the same seller link. If you already have weight sitting in another warehouse, consolidating there is usually cheaper than splitting a haul.
What does not change: you still review QC, you still pay freight, and customs still belongs to your country — not to the agent brand on the box.
