但是如果我訪問產品頁面：

https://www.amazon.com/gp/offer-listing/B002KT3XQM/ref=olp_page_1?ie=UTF8&f_new=true

我看到13個優惠。

是否有可能獲得全部13個優惠？

Answer 1

GetLowestOfferListingsForASIN打電話給你一個結果爲每組所謂的「限定符」。你舉的例子顯示了三種不同套這樣的預選賽：

• 手車VeryGood->適銷>道道通> 0-2天 - > 90-94％爲$ 32.99（包括shippng）
• 新建 - >新 - >亞馬遜 - >真 - > 0-2天 - > 98-100％爲$ 34.27
• 新 - >新 - >亞馬遜 - >真 - > 0-2天 - > 95-97％爲41.18美元

什麼我百思不得其解，是沒有新的「商人」的優惠被證明，當我真的認爲他們應該：

• New-> New-> Merchant-> True-> 0-2 days-> 98-100％將是不同的第四組限定符。

你真的好像在尋找的是一個不同的電話：GetLowestPricedOffersForASIN最多可爲單個ASIN返回20個不同的優惠。
