Amazon has changed a logic related to offers pages serving. Which blocked simple access to offers page.
Why scrapers cannot scrape Amazon offers page?
When you do a search, you can see that a product has some offers. If you click "offers" link, you can see all the offers. However, if you just inserted a link to the offers page into a browser and went to the product offers page, you would likely get an empty offers page.
You can't see offers page until you have some browsing history. We discovered that Amazon Data Extraction Engine could not see offers page because the offers page is blank if the visitor does not have certain cookies.
In this case, rotating proxies would not work, since we need to preserve cookies.
Important Amazon Data Extraction Engine update
Amazon tracks cookies for the offer page now. The only way to scrape offers by a robot is to generate a user-like behavior. It requires a reverse request order (first product page, second offers page) because offers page is always retrieved after the product page for the real browsing.
Our parser already works with cookies.
