Amazon.com has also an interesting promotion for U.S. shoppers on Prime Day: Earn $10 of credit if you let Amazon track the websites you visit.

The deal is for new installations of the Amazon Assistant, a comparison-shopping tool that customers can add to their web browsers. It fetches Amazon’s price for products that users see on Walmart.com, Target.com and elsewhere.

In order to work, the assistant needs access to users’ web activity, including the links and some page content they view. The catch, as Amazon explains in the fine print, is the company can use this data to improve its general marketing, products and services, unrelated to the shopping assistant.

Amazon already has more than 7 million customers using its assistant via Google Chrome and Mozilla Firefox, according to data published by those web browsers. Other companies offer similar shopping tools.

Amazon’s combination of tools still pales in comparison to data collection by Alphabet Inc’s Google, which has tracking pixels on most web pages.
