Price Comparison Tools: Why They're Essential
Shopping online without comparing prices is like buying blindfolded. Studies show that the same product can have a price difference of up to 40% depending on the shop. Price comparison tools help you find the best price and avoid fake discounts.
But which tool is right for you? We tested and compared the five most popular price comparison tools.
1. DealMonitor — The AI-Powered All-Rounder
What it does: DealMonitor tracks prices on any website — not just Amazon or selected partner shops. The AI-powered price detection finds the price automatically, regardless of page layout.
- Works on all online shops worldwide
- AI price detection (no manual setup)
- Price history with charts and CSV export
- Notifications via email, Telegram, and push
- Browser extension + web app
- Completely free
Best for: Anyone who wants to track prices across many different shops — not just Amazon. Especially strong for niche shops that other tools don't cover.
2. Keepa — The Amazon Specialist
What it does: Keepa is the most comprehensive tool for Amazon price histories. The browser extension displays detailed price graphs directly on Amazon product pages.
- Extremely detailed Amazon price history
- Marketplace and third-party seller prices
- Price alerts via email
- International Amazon markets
Limitations: Works exclusively on Amazon. No tracking on other shops. Some features require a paid subscription.
Best for: Power users who buy exclusively on Amazon and need maximum data detail.
3. CamelCamelCamel — Free for Amazon
What it does: CamelCamelCamel offers free Amazon price history data and price alerts. The browser extension "The Camelizer" adds price graphs to Amazon pages.
- Completely free
- Amazon price history going back years
- Simple price alerts
- Browser extension available
Limitations: Like Keepa, restricted to Amazon only. Significantly less detailed than Keepa. No marketplace or third-party data. Slow updates.
Best for: Casual Amazon shoppers looking for a simple, free solution.
4. Google Shopping — The Aggregator
What it does: Google Shopping searches the web for product prices and shows results from various retailers. Easy access since no installation is needed.
- Huge product database
- Price comparison across many shops
- No installation needed
- Integrated into Google Search
Limitations: No price history, no price alerts. Only shows current prices. Shops pay for placement — cheapest results aren't always on top.
Best for: Quick price checks before buying, when you don't need ongoing tracking.
5. Honey (PayPal) — The Coupon Finder
What it does: Honey automatically searches for coupon codes at checkout and shows price history on some shopping sites.
- Automatic coupon code application
- Price history on select shops
- Droplist feature for price alerts
- Browser extension available
Limitations: Coupon database is often empty for non-US shops. Price tracking is limited to partner shops. Owned by PayPal — privacy concerns. Does not work on arbitrary websites.
Best for: US-based shoppers who primarily want coupon codes alongside basic price tracking.
