Amazon Price Tracker n8n: Bright Data, Google Shopping & Slack

Amazon Price Tracker n8n (Bright Data + Google Shopping + Slack)

Run a daily Amazon price watch automatically: this n8n workflow scrapes your watched products with Bright Data, compares prices against your latest snapshot in Google Sheets, and posts a clear Slack brief when meaningful changes happen—plus it checks Google Shopping for cheaper competing offers.

What this workflow does

• Schedules a daily run and loads a watchlist of Amazon product URLs and alert thresholds from the workflow configuration.
• Scrapes latest Amazon data via Bright Data (price, stock, seller, rating, and rank) for each watched URL.
• Compares against Google Sheets history: reads the history tab, compares each product to its most recent prior snapshot, and flags events such as:
  • price moves beyond your configured percentage thresholds
  • stock flips
  • buy box seller changes
• Appends today’s full snapshot to the history tab to serve as the baseline for the next run.
• When changes are detected, checks Google Shopping using Bright Data’s SERP API for results and extracts the cheapest plausible new-condition competing offers.
• Generates a Slack-ready brief using OpenAI GPT-5.6, grounded in the collected numbers, then posts a concise sub-200-word update to your chosen Slack channel.

Use cases

• Monitor Amazon listings for your e-commerce sourcing or arbitrage portfolio and get instant Slack alerts on price drops or stock/buy box changes.
• Track competitor-related price movement and immediately see potentially cheaper alternatives surfaced from Google Shopping.
• Maintain an auditable price history in Google Sheets for reporting, auditing, or repricing decisions.
