How to Track Amazon Price Drops Automatically

May 14, 2026 · 5 min read

Amazon prices are unpredictable. That TV you've been eyeing can swing by $100 in a single day. Lightning deals disappear in hours. And Amazon's own price history? They don't show it to you.

Most people solve this with dedicated Amazon trackers like CamelCamelCamel or Keepa. These tools work well — but they have one major limitation: they only work on Amazon. If the same product is cheaper at Best Buy, Walmart, or B&H Photo, you'd never know.

Here's how to set up automatic Amazon price tracking that also works across every other store on the web.

The Problem with Amazon-Only Trackers

Tools like CamelCamelCamel are built exclusively for Amazon. They pull data from Amazon's product API and show you historical price charts. This is useful, but it creates blind spots:

• No cross-retailer comparison. You see Amazon's price history, but not whether Best Buy or Walmart has it cheaper right now.
• Only Amazon product pages. Want to track a price on Newegg, Adorama, or a niche electronics store? You'll need a different tool entirely.
• API-dependent. If Amazon changes their API or a product listing format changes, tracking can break until the tool's developers catch up.
• No element targeting. You track the entire product listing. You can't isolate a specific element like a "used" price, a shipping cost, or a third-party seller price.

A general-purpose website monitor like Webtracer solves all of these. It works on Amazon and every other site, tracks exactly the element you select, and compares prices across stores in a single view.

How to Track Amazon Prices with Webtracer

That's it. Webtracer will now check the Amazon product page at your chosen interval, extract the price, compare it to the previous value, and notify you if it drops.

Go Further: Compare Amazon vs Best Buy vs Walmart

This is where Webtracer's cross-site comparison feature stands out. Instead of creating three separate trackers for the same product on different stores, you can group them into a single tracker with multiple URLs.

Here's how:

1. Create the tracker on Amazon as described above.
2. Open the tracker settings and add URLs for the same product on Best Buy, Walmart, or any other retailer.
3. Select the price element on each site. Webtracer handles the fact that every store has different page layouts.

Now your dashboard shows all three prices side by side. You can see at a glance which store has the best deal — without opening multiple tabs or juggling separate tracking tools.

Tips for Effective Amazon Price Tracking

1. Click the right price element. Amazon pages have multiple prices (list price, deal price, "other sellers" price, Subscribe & Save price). Click precisely on the price you care about to avoid false alerts from unrelated price changes.
2. Track "Used" and "Renewed" separately. If you're open to used or renewed products, create a separate tracker targeting the "Other Sellers" or "Amazon Renewed" price element. This way you'll know when a bargain appears.
3. Use change history to verify deals. On Pro, Webtracer stores past values. Before buying during a "sale," check the history to see if the discounted price is actually lower than the recent average. Amazon occasionally raises a price before marking it down.
4. Add 2–3 stores to every tracker. Electronics retailers frequently price-match each other, but timing varies. The same GPU might drop at Best Buy two days before Amazon matches the price.
5. Set email alerts for high-value items. Browser notifications only fire when Chrome is open. For items over $200, email alerts (Pro) ensure you never miss a significant price drop.

Free vs. Pro for Amazon Tracking

The free plan gives you 20 trackers at 60-minute intervals with browser push notifications. For casually watching a few products, this is enough.

The Pro plan ($5.99/month) is worth it if you're tracking more than a handful of items, want 10-minute checks to catch short-lived deals, or need cross-site comparison and email alerts. If you save even $6 on a single price drop, Pro pays for itself.
