但是如果我访问产品页面：

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

我看到13个优惠。

是否有可能获得全部13个优惠？

Answer 1

GetLowestOfferListingsForASIN打电话给你一个结果为每组所谓的“限定符”。你举的例子显示了三种不同套这样的预选赛：

• 手车VeryGood->适销>道道通> 0-2天 - > 90-94％为$ 32.99（包括shippng）
• 新建 - >新 - >亚马逊 - >真 - > 0-2天 - > 98-100％为$ 34.27
• 新 - >新 - >亚马逊 - >真 - > 0-2天 - > 95-97％为41.18美元

什么我百思不得其解，是没有新的“商人”的优惠被证明，当我真的认为他们应该：

• New-> New-> Merchant-> True-> 0-2 days-> 98-100％将是不同的第四组限定符。

你真的好像在寻找的是一个不同的电话：GetLowestPricedOffersForASIN最多可为单个ASIN返回20个不同的优惠。
