Overview

Amazon permits sellers to present a single product in multiple condition states—such as brand‑new, refurbished, or used—but each condition must be entered as an independent offer. The platform then aggregates those offers on a single product detail page, letting shoppers pick the version that fits their budget or preference. Sellers who ignore the separate‑listing rule risk inventory errors, policy violations, and missed sales opportunities.

Key Points

• Separate offer per condition — A new‑and‑used version of the same ISBN cannot share one listing; each condition requires its own catalog entry.
• Unique SKU for every offer — Amazon uses the seller‑assigned Stock Keeping Unit to differentiate between a new and a used offer of the same ASIN.
• Single detail page, multiple offers — All condition‑specific listings appear on the same product page, allowing buyers to compare new, used‑like‑new, and heavily used options side by side.
• At least one differing attribute — When you clone an existing listing, you must change either the condition, the condition note, or the price to satisfy Amazon’s differentiation rule.
• Quantity is tracked per offer — Adding ten units of a used laptop updates the quantity field on the used‑condition listing only; the new‑condition listing remains unchanged.
• Condition notes drive buyer trust — A concise note such as “Minor scratches on the screen, fully functional” is required for used items and helps lower return rates.
• SKU naming conventions aid management — Prefixing SKUs with “N‑” for new and “U‑” for used lets inventory managers spot condition types at a glance.
• Low‑price matching is optional — Sellers can enable Amazon’s price‑match tool to automatically align their offer with the lowest price for the same condition in the marketplace.
• Buy Box eligibility is condition‑specific — A used offer competes only with other used offers for the Buy Box; it never contends with new offers.
• Policy compliance avoids account risk — Mislabeling condition or merging listings can trigger performance warnings or suspension of selling privileges.
