+- As of 2026-07, Rakuten Ichiba is a MARKETPLACE of independently operated "ショップ" (shops). Stable labels: "買い物かごに入れる" = add to cart, "買い物かご" = cart, and "ご購入手続き" = proceed to checkout.
+- Search results marked "[PR]" are sponsored. For a price comparison, use "同じ商品を安い順で見る" when available, then compare the exact variant's "価格+送料" and per-unit price; do not rank the first result or a bare "〜" price range as cheapest.
+- Select every size, color, pack count, delivery timing, and other required option before comparing or adding. "定期購入" is a recurring purchase with a different price — keep normal purchase selected unless the user explicitly asks for a subscription.
+- The cart is divided into boxes by shop. On desktop, items from different shops cannot share one checkout; mobile "おまとめ購入" may batch the steps, but each shop still creates a separate order and shipment. Read each box and click its own "ご購入手続き".
+- Shipping is shop- and destination-specific. A 39 Shop's 3,980円 free-shipping line applies within the same eligible shop and order, not across shops; "特定送料", remote regions, chilled delivery, and large items can remain chargeable. Verify every shop's cart total.
+- "ポイント", SPU, and スーパーDEAL are conditional rewards, not an immediate cash-price reduction; campaigns may require entry, membership, payment methods, or have caps, and shipping/tax do not earn ordinary points. Report the payable total separately from expected points.`,
