慢慢买历史价格比价 is a small plugin that allows users to quickly view the historical prices of products. It is compatible with popular e-commerce websites such as Taobao, JD, and Xiaomi Mall. By simply opening the product page on these platforms, users will see a "Go to 慢慢买" button in the bottom left corner. Clicking on this button will open the corresponding product's historical price query page.

It is important to note that due to 慢慢买's anti-web scraping measures, users may be required to verify their identity or log in using WeChat after opening the page.
