# tampermonkey-script-amazon-price-helper
Tampermonkey user script to view a price history chart as well as compare prices between stores from different countries.
You’ll understand it better with an example. This is a product page from Amazon:
And this is how you would see it once the script is installed:
# Install / update
You just need to have the [TamperMonkey](https://www.tampermonkey.net/) browser extension installed and click on this link:
https://github.com/aportela/tampermonkey-script-amazon-price-helper/raw/refs/heads/main/tampermonkey-script-amazon-price-helper.user.js
It’s possible that you’ll see an alert message from TamperMonkey notifying you that an script it’s trying to access a cross-origin resource (this is because the script makes a background request to the Hagglezone website to fetch the price comparison)
# Warning / Attention
Sometimes, the price scraping through external providers like Hagglezon fails because the service is too busy, and the product price list across different stores cannot be displayed.
This script DOES NOT INCLUDE AFFILIATES; no link or action is modified to add an affiliate for the purpose of earning money through commissions. Affiliates can appear on third-party providers pages, but this is beyond my control.
