Amazon All Offers & Buy Box Tracker

Amazon All Offers & Buy Box Tracker

Scrape every seller offer for one or more Amazon ASINs from the All-Offers-Display panel (the "Other Sellers on Amazon" / "See All Buying Options" list). Get condition, price, seller name and rating, ships-from, delivery estimate, and which offer currently wins the buy box -- for as many products as you need, across multiple marketplaces and destinations.

What this actor does

• Input by ASIN or by product URL -- mix and match freely
• Every offer, not just the buy box -- new, used, and third-party seller offers on the same listing
• Condition filter -- restrict to New, Used, Collectible, or Renewed only, or All (each matched exactly -- a "Used only" filter never silently includes Collectible/Renewed offers)
• Fulfillment type filter -- restrict to Fulfilled by Amazon (FBA), Fulfilled by Merchant (FBM), or sold-and-shipped-by-Amazon
• Destination-aware -- set a delivery country / postal code, since offer sets and delivery estimates change by destination
• Buy-box detection -- the current buy-box winner is explicitly flagged, never guessed from list position
• Empty fields are omitted

Output per offer

• productAsin -- the product ASIN this offer belongs to
• offerPosition -- 1-based order the offer appeared in on the page (buy box is always position 1)
• condition, subCondition -- e.g. "Used" / "Like New"
• conditionNote -- extra condition detail text, when Amazon shows one
• price -- { value, currency, display }
• unitPrice -- { value, currency, display }, when Amazon shows a per-unit price
• listPrice -- { value, currency, display }, the strikethrough "List Price" Amazon shows for this specific offer, only present when Amazon's own DOM carries it (typically the pinned/buy-box offer on a discounted item) -- never derived/computed
• savingsPercent -- integer percent-off (e.g. 30 for "-30%"), only present alongside a real listPrice
• deliveryEstimate -- the delivery promise text shown for this offer
• isFreeDelivery -- true/false, only when the delivery text gives explicit evidence either way (e.g. "FREE delivery..." vs. a stated shipping charge); omitted when ambiguous
• shippingPrice -- { value, currency, display }, only present when Amazon shows an explicit paid-shipping amount
• shipsFrom -- who ships the item
• soldBy -- { name, sellerId, profileUrl }
• sellerRating, sellerRatingsCount -- third-party seller reputation, when Amazon shows a rating line for that seller
• sellerPositivePercent12m or sellerPositivePercentLifetime -- the positive-feedback percentage, exactly one of the two depending on which real period Amazon measured it over (sellers with a full 12-month history get "% positive over last 12 months"; newer sellers get "% positive over lifetime" instead) -- never conflated into one field, since they cover different windows
• fulfillmentType -- "FBA" / "FBM" / "AMAZON", derived from Amazon's own "Ships from"/"Sold by" labels; omitted when the combination is ambiguous (e.g. a named third-party fulfillment center)
• isBuyBoxWinner -- true only for the pinned/buy-box offer, never inferred from position
• maxQuantity -- highest quantity selectable for this offer, when a quantity control is shown
• couponText -- any coupon/promotion text shown on the offer row
• marketplace -- { countryCode, domain, marketplaceId, currency, language }
• requestContext -- { productAsin, sourceUrl, canonicalUrl, deliveryCountry, postalCode }
• page -- { classification: "SUCCESS", totalOfferCount, moreOffersAvailable }. totalOfferCount is Amazon's own reported total offer count for the ASIN (when available). The actor automatically expands Amazon's own "See N more options" panel toggle before extracting, which fully recovers every offer on ASINs where Amazon had already rendered them all client-side (just hidden behind that toggle); on ASINs with a substantially larger real offer count, Amazon's client-side reveal itself only carries a further batch (not literally every remaining offer), so moreOffersAvailable: true can still appear even when maxOffersPerProduct was set higher than totalOfferCount -- this remaining gap would require a genuine server-side page-2 fetch the actor does not perform. Check this field rather than assuming maxOffersPerProduct was always fully honored.
• recordType: "offer", scrapedAt

Output: status records

When an ASIN's page can't be classified as a normal offers page (not found, invalid ASIN, sign-in wall, CAPTCHA, rate-limited, or a genuinely empty offers panel), the actor emits one explicit status record instead of silently returning zero rows. Likewise, when offers were found but every single one was removed by the conditions/fulfillmentTypes filters, one FILTERED_OUT status record is emitted (carrying Amazon's real totalOfferCount) so an empty result set is never ambiguous:

• productAsin, marketplace, requestContext
• page.classification -- one of NOT_FOUND, INVALID_ASIN, AUTH_REQUIRED, CAPTCHA, ROBOT_CHECK, DOG_PAGE_503, RATE_LIMITED, NO_OFFERS, FILTERED_OUT, etc.
• recordType: "status", scrapedAt

FAQ

What is the All-Offers-Display panel? It's the list Amazon shows when you click "See All Buying Options" or "X used & new" on a product page -- every seller currently offering that ASIN, not just the buy-box winner.

Why do offer sets change by destination? Amazon only shows offers a seller can actually ship to your delivery address. Setting deliveryCountry/postalCode makes the results match what a real shopper in that location would see.

Why is sellerRating sometimes missing? Amazon only shows an independent seller-rating line for third-party sellers. Offers fulfilled and sold directly by Amazon (or "Amazon Resale") don't carry a separate rating line, so the field is correctly omitted rather than fabricated.

How is fulfillmentType determined? From Amazon's own "Ships from" and "Sold by" labels on each offer row -- FBA (Fulfilled by Amazon) when Amazon ships it but a third party sold it, AMAZON when Amazon both sold and shipped it, FBM (Fulfilled by Merchant) when the ships-from and sold-by names match (the seller ships it themselves). If the combination is ambiguous (e.g. a named third-party fulfillment center), the field is omitted rather than guessed.

Why is isFreeDelivery/shippingPrice sometimes missing? Only set when Amazon's delivery text gives explicit evidence either way ("FREE delivery..." or a stated shipping charge). An ambiguous delivery estimate with no free/paid wording leaves both fields omitted rather than assuming free.

What's the difference between USED and COLLECTIBLE/RENEWED in the condition filter? Amazon's own AOD panel surfaces up to 4 distinct top-level condition buckets on the same listing -- New, Used, Collectible (rare/specialty copies, common on books/media), and Renewed (Amazon's official refurbishment program). Each conditions filter value matches its own bucket exactly -- selecting USED will never silently include a Collectible or Renewed offer. Use ALL if you want every condition together.

Does the conditions filter work on non-English marketplaces? The output condition field always shows Amazon's own real, localized text (e.g. Polish "Nowe", Dutch "Nieuw", Italian "Nuovo" for New-condition offers) -- it's never translated or altered. The conditions input filter itself recognizes the English bucket names plus a small, evidence-based set of live-verified translations: New-condition words for Polish/Dutch/Italian/German/Japanese/Spanish/French, plus Used/Collectible words for Japanese ("中古商品"/"コレクター商品"), German ("Gebraucht"), Italian ("Usato"/"Da collezione"), Spanish ("De 2ª mano"), and French ("D'occasion"). Filtering by USED/COLLECTIBLE/RENEWED on a marketplace whose offers render those buckets in a language this actor hasn't yet verified a translation for may under-match (real offers in that bucket excluded rather than risking a wrong match) -- use ALL and inspect the real condition text yourself if you need every bucket on an untranslated marketplace.

Why did I get a status record instead of offers? The ASIN's page didn't classify as a normal offers listing -- it may be invalid, geo-restricted, temporarily rate-limited, or genuinely have no additional offers beyond the buy box. The page.classification field tells you exactly why.

I set maxOffersPerProduct to 50 but got fewer offers back -- is that a bug? No -- maxOffersPerProduct is a cap, not a guarantee. The actor automatically expands Amazon's own "See N more options" panel toggle before extracting, which recovers every offer on ASINs where Amazon had already rendered them all client-side behind that toggle. On ASINs with a much larger real offer count (popular used-book listings with dozens of sellers are the most common case), Amazon's client-side reveal itself only carries a further batch rather than literally every remaining offer -- reaching the rest would require a genuine server-side page-2 fetch this actor does not perform. Every returned offer record's page.totalOfferCount/page.moreOffersAvailable fields tell you the real total and whether more exist beyond what was captured, so you can always tell the difference from a genuinely-exhausted result.

Is this affiliated with Amazon? No. This is an independent, third-party actor that reads Amazon's publicly viewable product pages.

How fresh is the data? Every run fetches the live page at request time -- offers, prices, and the buy-box winner can change within minutes on Amazon, so treat each run as a point-in-time snapshot.

Why does sourceUrl / soldBy.profileUrl return an error if I open it with a bare script? Amazon's edge blocks plain, cookie-less, non-browser requests outright -- a raw request from a clean script with no session/cookies will get a "Service Unavailable" response even though the same URL loads fine for a real shopper. This actor itself reaches these pages successfully; the URLs in the output are the correct, canonical Amazon URLs and will render normally when opened in a browser.
